HOwever the term overall came to refer to impressed and slip-inlayed ceramics in the Korean style like this bowl.

Startled to enlightenment, this is a large Edo period figure of a Rakan (Sanskrit: Arhat), a Buddhist saint kozutsucarved in the Yosegi-zaiku method of joined blocks of wood. Originally covered in polychrome colors, much has grayed and flaked away with time, a fitting aspect of the image. He has glass eyes which seem to burn violently with realization. The image is 43 x 36 x 51 cm (17 x 14 x 20 inches) and is in solid condition. The head is removable, slotted into the body at the collar. For additional images please inquire. In Buddhist lore the Rakan is one who has broken the chain of re-birth and overcome the three poisons of desire, hatred and ignorance. It is a popular theme in both Chinese and Japanese art. According to the Met: Rakan are ascetics who guard and proclaim Buddhist law on earth in the period between the death of Shakyamuni, the historical Buddha, and the coming of Maitreya, the Buddha of the Future. They have inspired some of the freest and most lively depictions of the human figure in Japanese art. Age and the struggle for salvation have left their mark, but in the figures’ gnarled faces and bodies is a strong expression of the uniqueness of each individual. Because Rakan achieved enlightenment through rigorous individual effort and meditation, they appealed to practitioners of Zen Buddhism and became a popular icon in medieval Japan. They are conventionally portrayed in groups of sixteen…

A bucolic scene of temples and rugged seaside hills dotted with pagodas in silver and gold wraps around the black surface of this deep tray dating from the Momoyama to early Edo period (16th-17th century). It is 27 cm (10-1/2 inches) diameter, 8.5 cm (3-3/8 inches) tall. The bottom has been re-lacquered at some time in the past. There is wear and cracks to the inside typical of age and use, and the rim has been re-done in gin-dame powdered tarnished-silver, which blends well with the ancient feeling of the piece.

An incredible lacquered screen decorated with a Bugaku Dancer wearing an angry devil mask opposing a snake in incredibly thick relief opposite three gentlemen heating sake over a fire under the changing leaves of a maple, their oxcart off to the side. An inlaid cartouche near the snake reads Kan. The two-sided panel is set into a frame with matt black iron texture over a raw kiri-wood panel inset with three windows. It is 45 x 16.5 x 40.5 cm (18 x 6-1/2 x 16 inches) and is in overall excellent condition, enclosed in an age darkened wooden box titled Haritsu Kenbyo. Off to the side a paper label gives a household collection number, and a further stamp shows it was recorded in an audit in Showa 14 (1939).
Ogawa Haritsu (1663-1747), also known as Ritsuo, one of the great individualists in the history of lacquer, was a poet as well as a painter, potter and lacquerer. Born into the samurai class, he renounced arms for the brush. In the 1680s, he became a disciple of the haiku poet Matsuo Basho (1644-1694). Haritsu turned to lacquer after 1707, the year his friends Hattori Ransetsu and Takarai Kikaku, both disciples of Basho, died. He adopted the art name Ritsuo, or "Old man in a torn bamboo hat," in 1712. The name suggests a poet or artist wandering carefree. A revival of interest in Haritsu's style and techniques during the 19th century is best exemplified in the copies of his work by Shibata Zeshin (1807-1891), the foremost Japanese lacquerer of the 19th century.

An unusual Edo period Oribe serving bowl, the color filled crackled glaze decorated with scrolling lines in iron and splashes of copper green. Both inside and out hash mars denote a bamboo fence with blossoms in the fore. A handle and raised architectural elements around the rim and rising to the mouth echo some western influence, possibly indicating original Christian use. It comes resting on a silk pillow in a age-blackened wooden box titled Oribe Katakuchi. The piece measure 24.5 x 13.5 x 10 cm (10 x 5-1/4 x 4 inches) and is in overall excellent condition.
On a little historical note, a toned paper label on one side denotes the piece was once placed under hold by the Himeji Courthouse as part of a property with a lean against it, indicating the piece was considered to be of significant value even a century ago.

A set of 5 rare Dutch glass cups imported to Japan in the Edo period and formerly owned by the Confucian scholar Nakai Riken (1732-1817). They are enclosed in a custom made double sided wooden box with drop in doors titled on the side Yoi-O-Gozui (Five fortuitous ways to be drunken) with a long verse carved into each door. Of course, the meaning of the title goes much deeper, and the Gozui is also a Confucian concept. The emperor of China distributed five jade treasures to the five feudal lords, and they were named. The scholar has named each of the cups after one of these jade objects, Ko, Yu, Haku, Shi and Dan. The Osaka University Professor Ueda Minoru researched Riken, and mentions the treasured set of five glass cups, the smallest with a golden rim, in his research of the scholars life and belongings, claiming them to be one of his most treasured items. The largest cup is 15 cm tall, the smallest 7.5 cm. There are some chips and fractures in the corners of the seven-sided foot of the smallest cup, otherwise all is in overall excellent condition.
Nakai Riken (1732-1817) was a Confucian scholar of the later Edo period. He studied Neo-Confucianism under Goi Ranshu, and together with his older brother Nakai Chikuzan, supported Kaitokudo, a school of learning in Osaka, leaving behind the greatest academic achievements of the Kaitokudo school. the rational and modern academic style that is characteristic of Kaitokudo literati was established mainly by Riken. As a scholar he commented on the classics and wrote books such as " Nanakyo Kadai," and "Shichikyo Kadai Ryaku." These were compiled into a total of thirty-three volumesara. He was well versed not only in economics but also in natural sciences such as astronomy. Goryu Asada, who had studied Western astronomy in earnest, stayed with. He wrote an overview of the ming period book "Tenkyo Arumon," by Yushiroku, and created a celestial map. In addition to astronomy, he also left a natural history map "Sakura Cho", an anatomical chart "Etsuryofutsu", and a microscope observation record "Microscopic Record". In addition, he wrote "Kashokoku Monogatari" (The Tale of Kashokoku), in which the protagonist was the king of a fictitious ideal nation, 'Kashokoku,' and discussed how the nation should be governed. A prolific writer, he left a vast body of contextual research for subsequent generations.

An unusual mask with gaping jaws and flattened features covered in red and black lacquer with golden teeth and eyes dated a lucky day in the 6th month of Tenmei 2 (1782). The mask is of carved wood covered in cloth over which has been applied layers of colored lacquer, gold and gofun (powdered shell) to form the white eyebrows. It is quite unusual in configuration. Most masks are open at the back, however this is carved with curling hair all the way down to the neck. Two holes in the teeth were likely so that the dancer could see out when the mouth was closed. The mask is 33.5 x 42.5 x 23.5 cm (13-1/4 x 17 x 9-1/4 inches). There are losses and cracks in the lacquer consistent with age.

A rare large vase by Kanzan Denshichi decorated with a hermitage in the hills and a poem extolling the beauty of summers first rain by Kanzan Denshichi enclosed in the original signed wooden box bearing the Shountei seal, dating it between 1871 and 1890. It is 34 cm (13-1/2 inches) tall and in excellent condition.
Kanzan Denshichi (1821-1890) was born in the ceramic-producing area of Seto. He worked at the Koto kiln of the Ii family in the Hikone domain, moving to Kyoto when the kiln closed in 1862. In Kyoto, he established his workshop at the base of Kiyomizu-zaka where he worked under the name Terao Denshichi and is thought to have been one of the first ceramicists in Kyoto to specialize specifically in porcelain. In the first year of the Meiji era (1868) he worked to supply the Kyoto Prefectural Office, following which he studied Western painting and pottery decoration under Gottfried Wagner. In the following three years, production was renamed Shountei and he worked under the name Kato Kanzan. Kanzan’s works include porcelain tableware, both Western and Japanese in style, often decorated with brightly colored polychrome and gold. Some of these wares were made for export, and Kanzan also exhibited at international exhibitions, securing a gold medal at Paris in 1878 In 1881 during their visit to Japan, Queen Victoria’s grandsons: Prince Albert Victor, Duke of Clarence and Avondale, and Prince George, Duke of York (George V), visited Kanzan’s workshop in Kyoto. The Imperial Household Ministry purchased Kanzan’s works, including some tableware for use in the Enriokan and other items in the style of the underglaze blue decorated Edo-period imperial porcelains known as kinri goyōtōki.
Pieces by Kanzan may be found in the collections of the Sannomaru Shōzōkan (Museum of the Imperial Collections) and Imperial Banqueting Department of Japan’s Imperial Household Agency, Tokyo National Museum and Kyoto Prefectural Library and Archives. The Victoria and Albert Museum has a pair of vases displayed at the Philadelphia Centennial Exhibition of 1876, a pair of ginger jars and four other small pieces. In 2014, the Sannomaru Shōzōkan devoted an exhibition to a Japanese-style polychrome dinner service made by Kanzan’s workshop for Prince Arisugawa Takehito: Beautiful Modern Kyoyaki (Kyoto-style ware) – Fine works by Kanzan Denshichi passed down within the Prince Arisugawa Family, 21 March – 22 June 2014.

Gargoyle or bat-like dragon-esque creatures spread their wings among tendrils of flame on the heavily decorated blue sides of this large pair of 19th century Sometsuke Japanese nesting bowls. Within boats ply the placid waters. The larger bowl is 24.5 cm (just less than 10 inches) diameter,10cm (4 inches) tall. The smaller is 21 cm diameter, 10cm tall and both are in excellent condition, dating from the 19th century.

A beautiful set of ten small shallow dishes, each uniquely decorated with a poem and image from the Edo period Sasashima Kiln of central Nagoya. The box, titled Sasashima Yaki Teshio Jumai (10 Sasashima Salt Dishes) is dated inside to the Tenpo era, (1830-1844). Each dish is 9 cm (3-1/2 inches) diameter and all are in excellent condition. Salt dishes were small plates used to hold salt, pickles or other condiments in a traditional Japanese meal. Finding a complete set like this in good condition is exceedingly rare.
The kiln producing Sasashima ware was opened by Makibokusai in the Bunka era in central Nagoya. Sasashima ware is characterized by its bright colors, and it is said that Makibokusai was also good at carving. The kiln, which continued for three generations after Makibokusai, is said to have disappeared around 1923 (Taisho 12) due to the expansion work of Nagoya Station.

An Edo period Kogo incense case of pale earth tones decorated with geometric shapes and green copper glaze in the oribe style with a scrawling streak of kintsugi gold extending down two sides. Kintsugi is the art of repairing using lacquer and powdered gold. Kintsugi is a traditional Japanese art form of repairing broken pottery or ceramics using lacquer and powdered precious metals. Instead of hiding the cracks and flaws, kintsugi embraces them and turns them into a beautiful and unique feature of the object. This practice holds several significant cultural and philosophical meanings in Japanese culture. The piece is roughly 7 cm (3 inches) diameter and comes wrapped in an antique padded silk wrapping cloth in an age darkened kiri-wood box with deer leather ties. The box is annotated Ko-Oribe Ume-gata Kogo (Old Oribe Plum-shaped Incense Container) by Seisai, (1863-1937), the 12th head of the Omotesenkei School of Tea. Kintsugi embodies the spirit of wabi-sabi, a Japanese aesthetic worldview centered around imperfection, transience, and the beauty of the natural cycle of growth and decay. Embracing the flawed and broken aspects of an object through kintsugi is a way to appreciate the passage of time and the history of the object, recognizing that it gains value and character through its journey. Kintsugi aligns with traditional Japanese values of frugality and resourcefulness. Instead of discarding broken items, kintsugi repairs them, extending their lifespan and reducing waste. This approach reflects a profound respect for resources and a desire to cherish and honor the objects used in daily life. This is also a way to avoid offending the spirit of the object, as all items are embodied with a soul of some sort. The act of repairing broken pottery with gold-laced lacquer carries a symbolic message of resilience and overcoming adversity. The restored object becomes a metaphor for the human experience, highlighting that even after suffering damage or hardship, one can find beauty and strength through healing and renewal. In the context of the Japanese tea ceremony kintsugi plays a vital role in enhancing the overall aesthetic experience, especially during the tenth month. The practice of kintsugi encourages contemplation and introspection during the tea ceremony. Guests may be reminded of the impermanence of all things and the beauty that can arise from embracing life's scars and vulnerabilities. Overall, kintsugi holds a deep cultural and philosophical significance in Japanese culture, symbolizing beauty in imperfection, respect for resources, and the resilience of both objects and individuals. In the context of the tea ceremony, it enriches the aesthetics and fosters a sense of mindfulness and appreciation for the present moment.

Tiny repairs of gold glint along the rim of this misshapen wan-gata bowl from the Utsutsukawa tradition of Nagasaki. The bowl comes with a silk pouch enclosed in an old wooden box. There is a kutsuki on one side, where it adhered to something else in the kiln. The bowl is 12 x 10.5 x 6.5 cm (4-3/4 x 4-1/8 x 2-1/2 inches) and is in overall fine condition, dating from the 19th century.
Utsutsukawa-yaki originated in Nagasaki in the late 17th century. It is said it began when Tanaka Gyobusaemon opened a kiln around 1690. It is characterized by brown orange clay with a heavy iron content and was most often decorated with Brush strokes in white slip. Although at one time it was called the Ninsei of the West, the manufacture lasted only about 50 years due to the financial aspect of the clan, and it disappeared until the Meiji period, when there was an attempted revival, but that too failed to last. In modern times the art was revived by Yokoishi Gagyu, and has been named an important cultural property of Nagasaki Prefecture.

The surface of this black glazed bowl signed on the base Dohachi has been impressed all over with seals in a style known as In-chirashi. It comes in an ancient wooden box with ebony rim titled inside Dohachi Saku (Chirashi-in) Chawan, while outside a much-worn paper label reads In-chirashi Dohachi Saku Chawan. The original silk pouch, much deteriorated, is included, but no longer strong enough to hold the bowl. Without a box signed and sealed specifically by the artist, it is difficult to attribute to an individual Dohachi, but likely this is the second Ninnami Dohachi generation. The gourd shaped seal impressed into the side strongly resembles the gourd shaped Momoyama Seal of Ninnami Dohachi II. The bowl is 11 cm (4-1/2 inches) diameter, 9 cm (3-1/2 inches) tall and is in excellent condition.
The Dohachi Kiln was established in Awataguchi by a retainer of Kameyama fief, Takahashi Dohachi I around 1760, and the name Dohachi was brought to the forefront of porcelain and ceramic production by the second generation head of the family who attained an imperial following, and grew to be one of the most famous potters of the Later Edo period to come from Kyoto. Ninnami Dohachi (1783-1855) was born the second son of Takahashi Dohachi I. Following the early death of his older brother he succeeded the family name, opening a kiln in the Gojo-zaka area of Kyoto (at the foot of Kiyomizu temple) in 1814. Well known for research into and perfection of ancient Chinese and Korean forms long held in high esteem in Japan, and at the same time working to expand the family reputation within tea circles. Along with contemporaries Aoki Mokubei and Eiraku Hozen became well known as a master of porcelain as well as Kenzan and Ninsei ware. Over the following decades he would be called to Takamatsu, Satsuma, Kishu and other areas to consult and establish kilns for the Daimyo and Tokugawa families as well as Nishi-Honganji Temple. Ninnami Dohachi II and his son (the future Dohachi III) were invited by the local lord Matsudaira to produce pottery at the Sangama kiln in Sanuki Kuni on the island of Shikoku in 1832. He would return later, agan with his son as well as his apprentice Siefu Yohei, in 1852. The third generation (1811-1879) continued the work of his father, producing an abundance of Sencha tea ware and other porcelain forms, maintaining the highest of standards and ensuring the family place in the annals of Kyoto ceramics well into the Meiji period. Takahashi Dohachi III began to use the title Kachutei Dohachi and was granted the title Hokyo by Ninaji-miya of the Imperial family. He retired to his grandfathers kiln in his later years, giving control to his son the fourth generation Dohachi (1845-1897) who also used the title Kachutei. The fifth generation (1869-1914) was adopted into the family and took head of the kiln in 1897 and was one of the top rated potters of his time, heavily influencing following generations including one of his top students, Ito Tozan. The kiln continues today with the 9th generation. The importance of the Dohachi workshop may be determined by the pair of vases held by the V&A (London) purchased in the 1870s under the orders: that they should 'make an historical collection of porcelain and pottery from the earliest period until the present time, to be formed in such a way as to give fully the history of the art. An exhibition was held at the Suntory Museum in 2014 centering on this artist, and he is also held in the Museum of Fine Arts, Boston and Kyoto National Museum among many, many others.

A large porcelain vase by) Daimaru Hokuho (Hoppo) enclosed in the original signed wooden box titled Yellow Porcelain Lightning Pattern Vase. The vase is a perfect example of the Sinophile aesthetic that permeated Japanese art in the early 20th century. The simplified form rises to a row of alternating concentric lines known as Lightning pattern. It is 21 cm (8-1/2 inches) diameter 25 cm (10 inches) tall and is in excellent condition.
Daimaru Hokuho (also called Hoppo, 1879-1959 ) would have been rated in the top 10 porcelain artist of Kyoto, along with Suwa Sozan, Ito Suiko, Ito Tozan, Miyanaga Tozan, Takahashi Dohachi, Seifu Yohei, Kiyomizu Rokubei, Miura Chikusen and Kiyomizu Zoroku, all artists active from the Meiji through the early Showa eras. He is best remembered for his Chinese forms and Sencha thin tea ware. Born in Ishikawa in 1879, he was initially trained in ceramic painting by Seishichi Okura at the Kutani Ceramic Company of the Kutani tradition before moving to Kyoto in 1899 to study porcelain throwing and decoration there. In 1906, he was invited to teach at the Hunan Ceramics Department in Hunan Province, China, and devoted himself to research on Chinese ceramics, returning to Japan where he took up residence again in Kyoto in 1909 and began making ceramics, mainly tea utensils and sencha utensils. He exhibited many works at exhibitions, receiving numerous accolades, and his works were purchased by the Imperial Household Agency. Daimaru Hokuho II (Tatsuo, b. 1926) studied under both his father as well as both Kiyomizu Rokubei V and VI. He exhibited frequently with the Nitten National Exhibition, where he would serve as a judge.

A set of three spouted nesting bowls decorated in the traditional Mugiwara pattern of alternating stripes of russet red, pale blue and orange emanating like rays from the center. The larger bowl is 9.5 cm (just under 4 inches) diameter, 5.5 cm (2 inches) tall. The smallest is roughly 7.5 diameter, 4.5 cm tall and all 3 are in excellent condition, enclosed in an old kiri-wood box.
This traditional pattern is called ``Mugiwarade'' because its vertical stripes resemble ears of wheat. It has three colored lines: green, red, and indigo and can be used regardless of the season. This pattern of regularly drawn lines was often used on utensils for daily use such as tea bowls, choko cups, and katakuchi cups. It is believed that they were made throughout Seto, including Shinano and Akatsu, from the late Edo period. Onita, which produces a brown color, is alternately painted with a paint called ``Akaraku,'' which produces a red or orange color, and Gosu, which produces an indigo color. You can see thick lines of red or indigo drawn with not just one, but two or even three thin brown lines between them. Drawing these lines at equal intervals and overlapping the lines thinly at the center (orientation) of the inside of the bowl or plate is one of the highlights of the craftsman's skill.

A small carved Zushi in the form of a cave housing a red stone in the shape of the Daruma, progenitor of Zen Buddhism in Japan. It is 6 x 4.2 x 8.3 cm (2-1/2 x 1-3/4 x 3-1/4 inches) and is in overall excellent condition, dating from the This would have been made as a talisman to ward off evil spirits. later Edo period.

Two Jubako stacking porcelain boxes enclosed in their unique wooden boxes which are both enclosed together in an additional outer wooden box for protection. According to the lid, the designs were by Kinoshita Itsuun and Uragami Gyokudo, and the pieces were made by Kawamoto Hansuke. Hansuke is considered the progenitor of porcelain production in Seto, and it was through an act of industrial espionage that he was able to bring the techniques, until then the secrets of the Kyushu potteries, to Seto. It is believed the 3rd generation Hansuke went to Kyushu, purportedly to help with the establishment of the Kameyama Kiln, and stole the secrets of porcelain production. Each set of boxes is roughly 12 cm (4-3/4 inches) square, 16.5 cm (6-1/2 inches) tall and enclosed in respective age-darkened wooden boxes. The landscape dominated pieces are in excellent condition, the boxes with floral designs have several small chips and one gold repair. The box for the landscape piece is titled Ju-bachi Hakurendo and has inside two long verses stating the paintings was performed by Gyokudo. The box for the second piece is signed inside Shintoen Hansuke-zo, the name used by the 4th generation Hansuke.
During the Horeki era (1751-1764), the first generation Kawamoto Hansuke worked with Kawamoto Jihei to build both the Asahi and Yuhi kilns, and each subsequent generation inherited the name Hansuke. The third generation switched to Sometsuke-yaki in 1804. His son, the fourth generation, took over the family business in 1822. He created a variety of Shozui-style dyed patterns and was a naturally talented artist, inheriting his father's legacy, and was always passionate about improving porcelain. 'In the Tenpo era, he finally invented the idea of pulverizing Gyaman stone and blending it with the original clay creating a lustrous, tranparent porcelain. During the Tenpo era (1830-1844), he was ranked as the Bishu family's pottery master. He is remembered as a person who made a significant contribution to the history of Seto's ceramic industry for his research into the use of silica stone as a glaze on porcelain to increase transparency and improve the color of Gosu, and for his efforts to improve quality.In 1858 (Ansei 5), he adopted Kawamoto Masukichi as his eldest daughter's son-in-law and passed the family business to him as the fifth generation.
Kameyama ware was made in Nagasaki during the late Edo period. The high-quality white porcelain is famous for its literati-style Gosu paintings reminiscent of imported Chinese models, but many designs evoke an exotic atmosphere unique to Nagasaki. A characteristic of Gosu is that it is darker overall than Imari. Under the Nagasaki Magistrate, the techniques of potters in each domain were handed down from generation to generation, producing highly skilled porcelain such as Mikawachi ware from the Hirado domain, Hasami ware from the Omura domain, and Arita ware from the Saga domain. In 1807, a kiln was opened in Kakineyama, Irabayashi, Nagasaki by 4 potters with funds by a loan from the Nagasaki Magistrate's Office, the kiln named Kameyama. The clay was taken from Amakusa, Ajiro as well as imported clay from Suzhou in China. Prominent literary figures such as Tanomura Chikuden, Kinoshita Itsuun, Somon Tetsuo, and Miura Gomon, designed elegant literati paintings for the pottery decoration. By 1819, it was run solely by Jingohei Ogami, and during the Kansei and Tenpo years it reached its peak, gaining reputation for its high quality. In 1839, Jingohei Ogami passed away at the age of 65, and the second generation, Jingohei, took over the kiln, which remained in operation until 1865. Because the pottery was produced over a short period of about 50 years, and there are few passed down items, it is called a phantom pottery, and particularly well-crafted pieces are prized by collectors.
Kinoshita Itsuun (1800 - 1866) was a nanga during the latter part of the Edo period. born as the third son of Kinoshite Katsushige in Nagasaki. At the age of 17 he inherited the role of "Otona," or village head, which had been assumed by the Kinoshita family for generations, but transferred the role to his elder brother in 1829. Working as a medical doctor, which had been his initial interest, he was committed to proliferation of vaccination learned from a Dutch medical doctor. Itsuun first learned Nanga painting from Ishizaki Yushi, as well as directly under several Chinese artists visiting Nagasaki. He ardently studied the techniques of various painting schools including Unkoku, the Kano School, Yamato-e and the Maruyama Shijo School as well as Western oil painting and incorporated them into his own technique. He tavelled in literati circles with the likes of Rai Sanyo, Tanomura Chikuden, Somon Tetsuo and Hirose Tanso. He also excelled in other fields such as calligraphy, tenkoku (seal-engra
