Important Notice Regarding Price Display Change and Consumption Tax

Thank you for your continued patronage.

We sincerely regret to inform you that due to the sharp increase in raw material costs and the commencement of our consumption tax obligations, we will be obliged to revise our price display as follows:

1. Price Display Change for Food Menu Items

Effective Friday, December 19, 2025, the prices for all food menu items will be changed to the “Exclusive Tax System” (displaying both pre-tax and tax-inclusive prices), and the consumption tax will be charged separately.

• Reason for Change: To cope with the significant rise in costs for our main ingredients and to fulfill our consumption tax payment obligations.

• Pricing Example: XX Set Meal: $¥980$ (Tax-inclusive $¥1,078$)

2. Pricing for Drink Menu Items (Prices Remain Unchanged)

To minimize the burden on our customers, the prices for our drink menu items will remain the same, maintaining the current tax-inclusive pricing.

• Display: The tax-inclusive price will continue to be the only price displayed, as before.

We assure you that the quality of our products will remain unchanged. Our entire staff will continue to strive for improved service to ensure your satisfaction.

Furthermore, our weekday exclusive service of a free large serving of rice will also continue.

We deeply apologize for any inconvenience this may cause and sincerely ask for your kind understanding.

December 2025
