Ko-Kinko Kogai

[Andi B.]

Hello,

from Utrecht Samurai Art Expo I brought this (mu-mei) Ko-Kinko Kogai.

Design is pomegranate and a clove.

 

I'm not familiar with Kogai, so I'm interested to learn a little bit more about e.g. which main categories/schools do we have (Ko-Gotô, Ko-Kinko, Ko-Mino,...?) and what are the differences.
I heard, that e.g. the Warabite and the shape of the "shoulders" have some importance to judge a piece, but of course I have no clue, in which way...

 

Any input (general and regarding this piece) is welcome!

Thanks!
