As miners brought their lunch boxes to work with them underground, their lunch was sometimes eaten up by mice.
Even though they took precautions, such as keeping their lunch box hanging from pillars off the ground,
mice often found a way to chew through the cloth they used to hang the lunch box and stoletheir food.
When this happened, miners found it difficult towork in the afternoon as they were weak on an empty stomach.
Lunch boxes were called KuragaiorGaga. The base of the lunch box was made of bamboo and the bottom made of cedar board.
