I guess a soldier was given the belt and pic respectively on different chance.

草津高女
サムハラ(kanji omitted)
サムハラ is a magic spell of fortune. I have seen similar one here.

草津高女 means Kusatsu Womes's Highschool, Shiga prefectre. Note that no personal name is seen on the belt. It seemed a senninbari prepared by high school girls and sent to soldiers randomly for local troops from Shiga or via imonbukuro. The army called cheering bag for soldiers and sent to units on the front randomly.

Considerably distant from Kusatsu. 喜廼葱 is mysterios but it looks like a restaurant's name. Her name 恵美香 (Emika). She might be a waitress, or geisha, or of some profession.
