Dear Sirs, We are pleased to announce that we are increasingly in good health. Thank you very much for your continued patronage.

Now, fuel prices have been rising due to the effects of exchange rates, and the prices of ceramic raw materials have been rising due to a decrease in production by raw material manufacturers, so clay prices have been increased by 25% across the board from August 2025.

Therefore, we regret to inform you that from September 1, 2025, we will be raising the prices of products supervised by Yazaemon and OKA SHINGO, as well as some products in STANDARD Series.

ARITA PORCELAIN LAB products have managed to withstand rising costs and avoid raising prices, but it has become impossible to maintain previous trading prices through management efforts alone. Thank you for your understanding.
