Form1 and Form2 are the basic forms required for anyone filing a Japanese Tax return. In Japanese Form 1 is called "Dai Ippyo (第一表)” and Form 2 is "Dai Nihyo (第二表)” These templates are faithfully recreated based on the official Japanese tax forms by a tax accountant, who is also the head of Ciel Tax (https://cieltax.jp/language/english/).
