Bell is hung in the Showrow, while drum is put in the Korou. These are arranged symmetrically from the Yomeimon Gate.

Size and structure of both buildings are relatively the same as each other, but there are small differences for decoration. For example, there are 78 sculptures including crane, dragon, flying dragon, giraffe and wave in the Showrow. On the contrary, there are 38 sculptures including turtle, dragon and cloud in the Korou. The Showrow is more gorgeous in terms of decoration.
