Amehata's history dates to Kamakura period. According to legend, in 1297, when Nichirō-shōnin 日朗上人, disciple of Nichiren-daishōnin 日蓮大上人(*daishōnin means a great sage) & one of The Six Elder Priests 日蓮六老僧, reached Amehata to erect a temple at Mt.Shichimenzan 七面山 by order of Nichiren, he accidentally discovered a blue and black stone at upstream of Amehata river and said an ink stone of fine quality would be made of the stone. The Amehata inkstone's full-scale production started under license of Shōguns 将軍 from one period of Edo era. In Meiji period, Association on manufacture & distribution of Amehata's inkstone was set up. According to data at that time, there were more than 90 artisans of inkstone in Amehata. But we have reduced the chance of using an ink stone & brush in our daily life and the number of them has also reduced. Currently there is only one person who works in Amehata.
Because the Amehata's stone is very close-grained, it is ideal for grinding an ink-cake[inkstick] 墨. The stone is mined from caves, near Mt.Inamata 稲又山, at upstream of the Amehata river.
Amehata suzuri costs from about a thousand yen to over 10 hundred thousand yen.
