Goto Hojo, given name Mitsuaki, was the sixteenth head of the main Goto house. The published sources record that he was born in Bunka 13 (1816), the third son of the fifteenth head Shinjo Mitsuyoshi, though two of them call him the fourth son; his childhood name was Mitsutoshi and his common name Shinjiro, later Gennojo. In the seventh month of Tenpo 6 (1835), when his father retired at fifty-six, he succeeded to the headship and took the name Shirobei Mitsuaki. He served as head for twenty-one years and died in the sixth month of Ansei 3 (1856) at forty-one. By his own memorandum he struck the Tenpo five- coin on shogunal order in Tenpo 8 (1837), and afterwards 1,887 ten- as well. The sentence the sources return to in almost every entry is that among the heads from the twelfth master Mitsumasa onward he is "said to be the most technically skilled".
His hand is the orthodox house manner, carried with unusual finish. The and are of in an even , carved in with gold and silver and backed with gold ('); the are carved in the round, in or in solid gold. On the set of the twelve zodiac animals the sources describe the and built by inlaying the plate, with long warabite feet, the backed with thick gold, and fine for the animals' coats, and they close that entry by saying that "Mitsuaki's true strengths are fully brought to bear". His colour is planned with care. On the falconry set and on the set of Noh implements he adds to the gold and silver, and the sources write that he "uses to good effect to bring in a rustic flavour". On a set for the Joshi festival he adds and the scarlet copper -do to the gold and silver, and there the sources judge the minute precision of the carving "unusual even within the Goto house", calling the set his masterpiece.
His subjects belong to the late and Bakumatsu taste. The seasonal festivals recur most: the standing hina of the third month, a whose fittings run through all five festivals, a of New Year, setsubun, Tango and Tanabata with rice ears, sparrows and a bird clapper on the , and a small-sword set of festival charms. Court music and dance, Noh and falconry implements, the house lions, the longevity deities Fukurokuju and Jurojin, the zodiac animals, wild boars, the salt-makers' shore and the flowers of the four seasons paired with poem papers fill out the rest. The sources note that his work is generally dense and rich, and they set apart a Sanbaso set worked almost wholly in , where "the black monochrome crest work is extremely precise". Of the lions biting an amulet pouch they write that the vigorous animals, together with "the Goto carving of high mountains and deep valleys", make a superb piece.
His signature is regular and is itself part of the record. He signs Goto Mitsuaki with a , and on the splits the given name between the pair as 光 and 晃. On especially careful work he cuts the full long signature, Goto Shirobei Fujiwara Mitsuaki, which the sources take as the mark of a deliberate piece. The most valuable of these is on the five-festival , whose and carry a commission formula with a date: 「応需嘉永三年春三月後藤四郎兵衛藤原光晃(花押)」, the spring of Kaei 3 (1850). On a bamboo-and-sparrow set signed in that long form, the sources read a strong influence of the town carvers in the branches, the placing of the birds and the treatment of open space. They connect that piece to a new official house carving that arose once the Goto were settled in , a reading resting on that one set.
He also stands in the record as a certifying head of the line, one generation before the Goto house came to its end. On a litchi set the crests are attributed to the ninth master Teijo, inscribed 紋程乗 with Mitsuaki's own name and beside it, and the sources record that the plates and the gold backing were made by Mitsuaki himself. That piece is evidence of his appraisal, not of his carving. On the lion set the sources observe that although "the long Goto line of metalworkers would end after one more generation", the work is spirited and "does not show the slightest sign of it".
His designated record is eighteen works: one and seventeen . The , first designated in 49 (1974), is a on the theme of court , every fitting signed in gold inlay, made for the Sannohe family after a design by the eleventh master Tsujo, its signed 「応需三戸氏以通乗図造之」. The sources call it "a fine work in which the height of Mitsuaki's technique can be felt". Five of the eighteen are complete or built around his fittings, and the rest are and matched fittings. He has no National Treasure or Important Cultural Property, and no current institutional holder is recorded; the Sannohe family is the one provenance named. Signed sets by him do appear from time to time, and a signed in with gold and silver is the form in which his work is most often met.
