United National Tag Team Championship

The Tenryu Project United National Heavyweight Tag Team Championship (天龍プロジェクト認定ユナイテッドナショナル・ヘビー級タッグ王座) is a professional wrestling tag team championship contested for in the Japanese promotion Tenryu Project. This title is the first championship in Tenryu Project that is not revived from Wrestle Association-R. It is also referred to as the UN Tag Team Championship (UNタッグ王座) for short. The title matches are fought under PWF rules.

History
The title was created in April 2023 with the approval of All Japan Pro Wrestling (AJPW) and Dory Funk Jr., chairman of the Pacific Wrestling Federation (PWF), the governing body for AJPW's championships. It was created to honor the career of Genichiro Tenryu, who held the NWA United National Championship two times before it was unified into the Triple Crown Heavyweight Championship. The title matches are fought under classic PWF rules which make all matches 2-out-of-3 falls with a 60-minute time limit.

Inaugural tournament
A one-day four-team tournament was held on June 10, at the GEN Sports Palace in Shinjuku, Tokyo, to crown the inaugural champions. The Aoyagi brothers, Yuma and Atsuki, representing AJPW and their stable Zennichi Shin Jidai, ended up winning the tournament.

Belt design
The Tenryu Project United National Heavyweight Tag Team Championship belts are almost exact replicas of the old NWA United National Championship singles belt, originally made in 1970 and retired from use for the Triple Crown since 2013. They feature the same six side plates on a black leather strap. In the center plate, the word "TAG" has been added between the "UNITED NATIONAL CHAMPION" inscription and the globe. Instead of a red leather background, one of the belt has a yellow background, while the other has a blue background. Instead of a depiction of two grapplers, the globe features a kanji in black enamel; the yellow belt reads "阿" while the blue belt reads "呍". Together, those kanji form the word A-un (阿呍). In Japanese buddhism, it is the syllable representing the primordial trinity of Vishnu, Shiva and Brahma, and is akin to the idea of the "Alpha and Omega" (although the spelling 阿吽 is more common).
