Currently, there are several Vietnamese Buddhist temples in Japan,[1][2] with Chua Vietnam in Aikawa being one of the largest as of 2024.

[4] Tuyền was born in Bình Thuận province in southeastern Vietnam, and after graduating from a Buddhist school, he worked as abbot at a temple in Ho Chi Minh City.

[4][6] Aikawa was selected as the temple site due to its affordable land and abundant natural resources, such as rivers and mountains.

[8] Tuyền observed the natural features of Aikawa Town and concluded that it was a suitable environment for ascetic practices.

[7] Today, Chua Viet Nam has become a common spiritual center for the Vietnamese community in Japan.

[10] People gather there to make offerings to their ancestors, pass on Vietnamese culture to their children, and consult with monks about their problems.

Every weekend, Vietnamese residents in Japan gather from Sagamihara, Atsugi, Ebina, Isehara, Hadano, and other nearby cities and towns,[7] as well as from Tokyo, Saitama, and as far away as Nagoya.

[8] According to an interview with Abbot Nhuận Ân by a Vietnamese newspaper, he is actively trying to build a relationship with the local community in order to reduce the concerns of the surrounding residents due to noise and parking spaces as the number of worshippers increases.
