On July 1, 2022, the JPO announced that search fees will be revised for international searches conducted by international search organizations other than the JPO starting next month.
This revision is due to adjustments resulting from the recent and ongoing depreciation of the yen, which has resulted in a larger price increase.
Payment by July 31, 2022: 229,300 yen
Payment on or after August 1, 2022: 245,500 yen
