The two-day event aims to promote Vietnam’s images to Japanese friends, and part of efforts to restart cultural and people-to-people exchanges between Vietnam and Japan.
COVID-19 preventive measures have been in place to ensure safety for festival-goers.
This is one of the largest annual festivals in Tokyo, which promotes Vietnamese cuisine and culture to Japanese people, Charge d'Affaires of Vietnam to Japan Lam Thi Thanh Phuong said.
The festival was first held in Japan in 2008, when the two countries celebrated the 35th founding anniversary of diplomatic ties, she added.
Japanese Parliamentary Vice-Minister for Foreign Affairs Miyake Shingo said about 450,000 Vietnamese are living in Japan, and Vietnamese dishes are favoured by local people.
Vietnamese and Japanese musical performances are staged at the event.
