A commemorative day created by the Japan Bath additive Industry Association with the purpose of marketing bath salts. It was set to this day because of the pun with the words "good bath"!
The pun: good bath → ii furo in Japanese.
Ii: 11
Furo: fu (2 in the hifumi numbering system) + ro (short for roku, 6 in the ichinisan numbering system)Taking a bath with bath salts has such a special feeling to itThis is wonderful~siiiigh
