[Event Overview]

The "International Abacus Classic 2026," an international abacus competition bringing together children from around the world, will be held for the first time this year in Portland, Oregon.

Approximately 180 competitors and 100 staff members from Japan, the United States, and Canada are expected to participate.

Abacus calculation is not merely a computational skill; it is being reevaluated worldwide as an educational method that fosters essential life skills such as concentration, memory, perseverance, and self-management.

This tournament will not only provide an opportunity for children from various countries to compete and showcase their daily achievements, but also to foster friendships through cross-border and cross-cultural exchanges, helping them grow into the next generation of global citizens.

Furthermore, 2026 marks the 35th anniversary of the sister-state relationship between Oregon and Toyama Prefecture. Visits by government and education officials from Toyama Prefecture are scheduled during the competition, and the event is anticipated to serve as a symbolic occasion for educational and cultural exchange.

Furthermore, the opening ceremony will feature the raising of the Japanese and American flags as well as an international exchange program, making this a tournament that connects the local community with the world.

We hope that everyone in North America, including those in the Seattle, San Francisco, San Jose, San Diego, Los Angeles, and Portland areas, will have the opportunity to witness world-class abacus competitions and international exchange.


[Connection to the 35th Anniversary of the Oregon-Toyama Prefecture Sister State Partnership]

The year 2026 marks the 35th anniversary of the sister state partnership between Oregon and Toyama Prefecture. The International Abacus Classic 2026 is positioned as one of the educational and cultural exchange initiatives held during this milestone year, playing a role in passing on the long-standing friendship between Toyama Prefecture and the State of Oregon to the next generation.

Abacus calculation is one of Japan’s traditional educational cultures that the country takes pride in sharing with the world, and at this competition, children gathering from around the globe will learn from one another not only through competition but also through cultural exchange. The International Abacus Classic 2026 is expected to serve as an opportunity to further deepen the bond between Oregon and Toyama Prefecture through educational, cultural, and international exchange.


[Organizer’s Comment]
