The races in question are Rounds 6 and 7, to be held at Sugo and Autopolis respectively.
Super GT has moved to avoid a clash between the Sugo race and the Fuji round of the World Endurance Championship by shifting its annual trip to Japan's Tohoku region back a week to 16-17 September.
The Autopolis round was previously scheduled for 30 September-1 October, but will now instead take place two weeks later on 14-15 October.
This creates a clash with Petit Le Mans, the IMSA SportsCar Championship finale, although it does also eliminate an overlap with the GT World Challenge Europe curtain-closer in Barcelona.
The start of the season is still scheduled for 15-16 April at Okayama, with Motegi again set to host the final round of the eight-race season on 4-5 November, three weeks after the revised Autopolis date.
Race distances for the 2023 season, as well as pre-season testing dates, have yet to be announced.
