About four to five hundred years ago there were Japanese in Southeast Asia on a somewhat large scale for a short time. One of the communities was in southern Vietnam. The Japanese then integrated and intermarried with the Vietnamese. Some were Japanese merchants marrying with a prominent Vietnamese family, the Nguyen, which is the most common Vietnamese surname.
In World War II, Japan conquered Vietnam and maintained a military force there until they were defeated in 1945.

Recently Japanese have come to live in Vietnam, especially in the capital, Hanoi. Professional work, such as finance and manufacturing., is the main attraction for Japanese moving to Vietnam. Businesses such as Honda have come to Vietnam. Japan is the largest donor to Vietnam. There are Japanese restaurants in Vietnam, and Japanese language education has become popular in there.

The main religions of the Japanese are Shintoism and Buddhism. The Japanese speak Japanese and Vietnamese.

The Japanese in Vietnam need the spiritual hunger it takes to seek and find the Lord.

Pray that the Holy Spirit draws Japanese businesspeople to seek, and find, Jesus Christ.
Pray for Vietnamese Christians to lead discovery Bible studies especially for the Japanese.
Ask the Lord to send dreams and visions to Japanese leaders in Vietnam, and that Christians will be ready and willing to explain those dreams and visions.
Pray that Vietnamese Christians will be a beacon of light to the Japanese.
