幅(はば)、長さ(ながさ)、高さ(たかさ)がそれぞれ約(やく)3メートルの非常に(ひじょうに)小さな(ちいさな)小屋(こや)

Tired of worldly status and success rivalries, Chomei abandoned everything in his mid-fifties and entered the mountains. In the mountains of Hino, Kyoto, he built an extremely small hut ('Ian') measuring only one 'jo' (about 3 meters) in width and length, and one 'jo' in height. This is the origin of 'Hojo,' the title of the book.
