On 5 November 2026, Anderson Mori & Tomotsune announced on its website that it will open its first U.S. offices next spring in Texas. The firm said Texas is a state where Japanese companies are rapidly expanding. It said the two offices, in Dallas and Houston, will provide flexible support to meet the increasingly sophisticated needs of U.S. business law. The firm published the announcement in English and in Chinese.[15][18]
Asian Legal Business covered the move on the same day under the headline "Anderson Mori becomes latest Japanese firm to say howdy to Texas".[13]

The other is an instalment in a series on China's economic security legislation and practice (中国の経済安全保障法制と実務), reviewing 2026. The firm's site lists a seminar for 18 December 2026 on first response and contract practice when a dispute arises in an overseas transaction (海外取引トラブル発生時の初動対応と契約実務).[16][17][20]
