Overview
Box Hako (箱 -はこ- in Japanese), often just "Hako" for short, is a game created by Japanese H-game company, Illusion and released on October 10, 2008.
The gameplay involves a mysterious box sitting on the player's table, inside which is a doll-house like room environment where fairy-sized girls live (only one at a time). The player can observe, interact from outside (poke, give food, etc), and even shrink himself and enter the box at the same size as the girl.
