|Japan Good Conduct
This is a group mainly concerned with supporting volunteer activities. Affiliated with the
government Cabinet Office. It was established as a corporation on June 10, 1949, but it seems
to have existed in a different form from 1937 to 1948. So some of the badges and medals may
be pre-war. However, if the term 'Shadan Houjin [corporation]' appears on the piece, it would
certainly be post-1949.
The name of the group is Shadan Houjin Nihon Zenkou-Kai, Japan Good Conduct Corporation.
There seems to be three main medals, gold, silver, and bronze.
