2023 Karuizawa International Curling Championships

The 2023 Karuizawa International Curling Championships were held from December 1 to 3 at the Karuizawa Ice Park in Karuizawa, Nagano, Japan. The total purse for the event was ¥ 1,500,000 on both the men's and women's sides.

In the men's final, Brad Gushue and his Canadian championship team of Mark Nichols, E. J. Harnden and Geoff Walker capped off an undefeated run by defeating Sapporo International University's Hayato Sato 7–1. The team from St. John's, Newfoundland and Labrador dominated the championship game, getting out to an early three-point lead and stealing two in the seventh end to secure the win. Niklas Edin took third in the men's division with a 9–3 thrashing of Karuizawa's Yusuke Morozumi.

In the women's final, Chubu Electric Power snapped the ten-game win streak of South Korea's Kim Eun-jung to win their first tour event of the 2023–24 season. The team, including skip Ikue Kitazawa, Seina Nakajima, Ami Enami, Minori Suzuki and Hasumi Ishigooka took control of the final game with three in the fourth end and held on for a 7–6 victory.
