When we first opened, we maintained a flat rate of 150 yen, and have maintained that flat rate for over 300 years since then. However, due to the recent rise in raw material and logistics costs, as well as the current economic backdrop, we are no longer able to provide satisfactory service to our customers at our previous prices. Therefore, starting November 1, 2025, we will be changing our current flat rate of 300 yen to a new flat rate of 385 yen (tax included, excluding some products).
