- Koma is anything < 4.5 mat. Hiroma is anything > 4.5 mat. Yojohan is a special case that can act as either
- Koma cannot use tana, and koma is always ended with honjimai
- Koma is very informal, so this is balanced with the more formal ending pattern (honjimai).
- Hiroma, you can use anything, and you always end with nakajimai if you can (regular hakobi, regular tana, or tsutsumibukusa/ootsubukuro/nagao). This includes for Yojohan.
- Consequently, sotozumi ←→ honjimai, and vice versa
- Komazue is when you have a hiroma but you arrange the temaeza to be like koma — that is, you place the furosaki such that you walk directly onto the temaedatami, not onto a fumikomidatami.
