Artist: Kitagawa Utamaro [喜多川 歌麿] (Japanese, c. 1753 – 1806) "This uncommon half-size horizontal ōban ... is most likely one design from a set of twelve prints issued late in Utamaro's life" [Japanese Erotic Fantasies, Hotei Publishing, 2005, p. 143, pl. 47].  Half-size horizontal ōban must be 12.7 x 38 cm. Richard Waldman and Chris Uhlenbeck say it's tanzaku size (13 x 43 cm). In reality, the prints of this series measure 17 x 38 cm, which corresponds exactly to horizontal o-hosoban paper size. I managed to assemble 11 of allegedly 12 designs. 7 of them have genitals colored by hand. It's hard to tell whether it was done by the publisher on demand of a peculiar buyer, or by the owner of the prints who considered the black and white privy parts unnatural. My sequencing of the prints is arbitrary. Transcription of the text may help find the correct order. As Japanese Erotic Fantasies put it: "a couple engaged in love-making, their stare fixed outside the picture plane". This is the only image of series that has a reference in available western literature, and the only one found in museum collections: Rijksmuseum Amsterdam (RP-P-1999-2001-16); reference: Fukuda (ed.) (1990), pls. 11-2. The scene of this print looks quite similar to that of the Kiyonaga's Sode no maki:  The woman is "a young lady-in-waiting of Shogun's Court or Daimyō's Mansion, enjoying a rare outing from her tedious chores" [Richard Lane]. She is fully dressed in her outer cloak (shikake), white paper hat (agebōshi or tsunokakushi), and toed socks (tabi).  A book or maybe, onkotogami (roll of tissues known as 'paper for honourable act' ) is still in the folds of her kimono. She is holding an open fan, either to cover her and her lover's faces from an unsolicited witness or to bring some fresh air to their joined lips. The pair just started their sexual intercourse. A scene from medieval times. A courtier in eboshi cap having sex with an aristocratic young woman with a long straight hairstyle (suihatsu). Completely naked couple in the moment of ejaculation. Lavish garments with paulownia leaves on a yellow background counterbalance the white bodies on red bedding. The form of a woman's cheeks is telling, but I don't know about what. Maybe her advanced age? The pose of the couple and the overall composition are similar to that of the previous sheet. Though the lovers are dressed, and the woman's hairdo is well kept. The male looks older and the woman - younger.   A man takes a young maid from behind. She clenches the sleeve of her kimono in her teeth; it's either the moment of penetration (beginning of intercourse) or of her orgasm (the end of it).   This seems to be a forced intercourse between a lackey with extensive bodily hair and a young maid from the same household. This design is very much like the other one presented below, which is described at Japanese Erotic Fantasies on page 136 (pl. 43b) as follows: "The viewer peers through a mosquito net to see a child fast asleep, while his mother or wet-nurse moves towards her partner. On our print there is no child; instead of a sleeping baby, there is a roll of onkotogami. Fewer objects make the overall image concise, almost laconic in comparison with the Ehon hana fubuki (1802) design: A young couple in a moment of true love. He is listening to the beating of her heart. This is a moment of true love between an old monk and a young samurai. The latter even did not take of his socks (tabi). From Japanese Erotic Fantasies: "Boats played a crucial role in the workings of Yoshiwara, as they were the primary means of transport to the district. During the hot summer months, trips on pleasure boats were also a favourite pastime. Sex aboard a boat is a recurrent theme in shunga". The last print that I am currently lacking and hunting for: I know where it is, but I cannot reach it... yet.

Kitagawa Utamaro. According to Chris Uhlenberg this is an illustration from the book Ehon koi no Onamaki, 3 vols, published in Kansei 11 (1799). Illustrated in b/w in: Hayashi Yoshikazu: Kitagawa Utamaro, in the series: Edo makura-e shi shusei, published in 1990, reissued 1994. Size: Chuban (25.5 x 18.5 cm), two book pages glued together.  

Katsukawa Shun'ei. The Sumo Bout between Yotsuguruma (right) and Yamaoroshi (left). Date: 1800 or 1805/06. Similar sheet can be found at Edo Tokyo Museum. Size: Vertical Ōban. Sumo wrestler Yotsuguruma Daihachi (1772 - 1809) first appeared in the records of national tournaments in winter of 1794. Then he lost 3 matches and won zero. He first won in the spring tournament of 1797 in a match against maegashira (the fifth-highest rank of sumo wrestlers) named Kougamine. Yamaoroshi Gengo (born 1762) came in at the winter tournament of 1799 . He was much more successful in his career than Yotsuguruma, but he had never won a tournament. It was the time of great Raiden, who won most of them. In the spring tournament of 1800 Yotsuguruma and Yamaoroshi fought against each other for the first time. Yotsuguruma lost. The next time they met on the ring was at the winter tournament of 1805, and again in 1806. Both matches were won by Yamaoroshi. Yamaoroshi retired in 1809; Yotsuguruma died in 1809.  

This information has some inconsistencies already. If our hero was born in 1807 and promoted to ōzeki at the age of 32, it should have been the year 1839, not 1847. I found Kumagatake Isuke at "Sumo Reference" website:

Highest Rank	Maegashira 4
Real Name	Kuroki
Birth Date	1815
Shusshin	Kumamoto-ken, Kuma-gun
Death Date	March 6, 1855 (40 years)
Heya	Oitekaze
Shikona	Kuroyanagi Matsujiro - Kumagatake Isuke
Hatsu Dohyo	1836.02 (Sandanme)
Intai	1853.02

The real name is the same, the ring name Kuroyanagi Matsujiro is the same, however, the date of birth here is 1815.  He fought from 1836 till 1853 - which is quite similar to "At the age of 31 he went to Edo, and became a disciple of the ōzeki Oitekaze Kitaro". Though, in 1836 he might be 29 years old. His bouts are listed from spring 1841 to spring 1848 under the name of Kuroyanagi and from winter 1848 till spring 1853 he listed under the name of Kumagatake Isuke [Inosuke].

On another important sumo history website, I found that Kuroyanagi first appeared at ring in the spring of 1823 (he might have been 16 years old then, which does not seem right). Then, in the winter tournament of 1848 Kuroyanagi took the name Kumagatake. At the spring tournament of 1853 Kumagatake (Kuroyanagi) retired. This is quite consistent so far.

Then, I found Oitekaze Kitaro, allegedly the teacher of Kuroyanagi.

Highest Rank	Ozeki
Real Name	SATO Matsujiro (Matsutaro#)
Birth Date	1799
Shusshin	Kanagawa-ken, Tsukui-gun
Death Date	May 4, 1865 (66 years)
Heya	Oitekaze
Shikona	Kuroyanagi Matsujiro - Kuroyanagi Sumiemon - Oitekaze Kitaro
Hatsu Dohyo	1817.10 (Jonokuchi)
Intai	1839.03

Everything look good with an exception of ring names (shikona): Kuroyanagi Matsujiro (1823-1828) - Kuroyanagi Sumiemon (1829-30) - Oitekaze Kitaro (1831-1839). May it be that Sato Matsutaro fought under the name of Kuroyanagi Matsujiro until Kuroki Matsujiro took this name from his master? I don't have another explanation of the enigma. What we know is that we have a portrait of a sumo wrestler called Kuroyanagi Matsujiro from Kyushu, but we don't know whether this was the one from Kumamoto (Kumagatake Inosuke, 1807/1815-1855) or the other from Kanagawa (Oitekaze Kitaro, 1799-1865). Subsequently, we may declare that the artist is Shunsai Eishō, a.k.a.Harukawa Eichō from Eishi school (The Hotei Encyclodepdia, p. 524), we can date the print from 1818 to 1844, and only tell that the wrestler is Kuroyanagi Matsujiro from Kyushu (either Kumagatake Inosuke or Oitekaze Kitaro). The publisher of the print is Moriya Jihei (Marks №353, p. 243-5). That's it.
