Special feature: Minosuke Fuji Naotane was born in Ansei 7 in Dewa Kuni Yamagata, and his real name is Shoji Minobei, and he was named also as Taikei. In around Bunsei 4, he had succeeded to Chikuzen Daijo. In Kaei 1, he had moved to Kyoto and became Mino Kami. He moved to Edo when he was still young and became a pupil of Suishinshi Masahide. And later he worked under Akimoto Ko like his master, and learned with Hosokawa Masayoshi. The date when he became a pupil of Suishinshi Masahide is unsure, but because we can find Mei of “Shoji Naotane Kansei 13 Shogatsu Hi” with the product made by him at the age of 23, it could be estimated around Kansei 11 or 12. And he had to be independent around Bunka 1. He passed away on 7th of May, Ansei 4, at the age of 79.

From Aoi Art: He travelled 3 times a year, so we find many works with Mei engraved in different places. He started his travel from Mishima Shrine in Izu, and through Nirayama, Shuzen Temple, Enshu Hamamatsu, Ise Hisai, Ise Shrine, and got back to Edo. Naotane could both Bizenden and Soshuden, and he was good at both. Bizenden works of him tend to have Utsuri like this work. It is very rare for the works made in the late Edo period to have Utsuri like this.
