Chambara stamp

There was no stamp for it This was unacceptable. So I made one.

(From Wikipedia)
In Japan, the term chanbara (チャンバラ^?), also commonly spelled "chambara", meaning "sword fighting" movies,^[1] denotes the genre called samurai cinema in English.

Chanbara is a sub-category of jidaigeki, which equates to period drama.
