庫 warehouse

We got a warehouse full of cars and an orphanage full of KODOMOS (子)

We use the cave as a warehouse to keep all our cars in.

the fuckin' fridge ★★★★☆
冷 (cold thing) + 蔵 (traditional storehouse) + 庫 (warehouse) = 冷蔵庫 (the fuckin' fridge )

a safe ★★☆☆☆
金 (gold) + 庫 (warehouse) = 金庫 (a safe)
