On May 6, 2022, the JPO updated the list of designated fees for international applications for designs under the Hague Agreement.
There are two types of international filing fees for designs: a transmittal fee paid to the Japan Patent Office when filing an international application through the Japanese Patent Office, and a fee paid directly to the International Bureau (WIPO).
The respective fees are listed on the JPO website.
