The Vibrants convincingly clinches Japan Team Chess Championship 2025
Japan Chess Federation hosted the 2025 edition of the annual Japan Teams Chess Championship, typically held in the pleasant weather of Autumn. When the Japan Open is held earlier in the year, the Teams event happens to be the last major event of the calendar year. This event holds a special memory, as the 2023 edition was my very first event as an arbiter. The experience led to bigger and better things, eventually leading to me becoming a FIDE Arbiter earlier this year. I may eventually want to play in this event, as well as arbitrate in future events. This year was the time to take a break and write about the event. Photo: Japan Chess Federation


The 2025 edition of Japan Team Chess Championship comprised of two categories, namely, the Open and the Group A. Group A consisted of teams with an average rating of less than 1400.

A special thanks to Tokyo Check Mates Chess Club, for providing their games and photos from the event. Tokyo Check Mates fielded 9 players over two teams in the Open section, viz, Tokyo Check Mates Kuro and Tokyo Check Mates Shiro, aptly named for a chess tournament (Kuro = black, Shiro = White). Kuro was the stronger of the two teams.
One of the best performances was the fifth place finish by “Tokyo Check Mates Kuro”. Led by their able captain Azizjon Mamatkulov (JPN) originally from Uzbekistan, this multi-nation, multi-lingual team comprising of Axel Martin from France, Vedat Erkoc from Turkey, and Thiele Leander from USA. Martin Axel from France tied with Azabu OB with a score of 9 points, with 4 wins, a draw and a loss.
Vedat Erkoc, and captain Azizjon Mamatkulov, scored 4/6 on boards 2 and 4. Both of them scored seventh place on tie-breaks in the board prizes (tied with four others).
Tokyo Check Mates is a very friendly, casual club, handled by Michael Hold, that meets on Wednesday evenings at Shibuya.
Kyoto University Chess Circle fielded two teams, one in the Open category and the other in Group A. Both the teams punched above their weight, with Kyodai Chess Circle finishing third on tie-breaks in Group A.
Yuya Yanai who has started a chess meetup in Kyoto, participated with team “Brilliant” and shared some photos.
Divine Chess Gurukul, a Gurukul style chess club run by Mr. Praveen Bhatia, which hosted the simul events by GM Swayams Mishra after the recent Japan Open 2025, also fielded two teams. “Brave Queens of Gurukul” - the team full of youngsters, became an excellent opportunity to gain experience in leadership, management and being a team player.
