Many Japanese people immigrated to America in the early 1900's, primarily to Hawaii and California to pursue available agricultural opportunities or work on the railroad. In the 1940s, many Japanese people settled in Utah. In the Dai-Ichi ward some members have not mastered the Japanese language and some have not mastered the English language. Adult classes are offered in both. Youth classes are in English since that is what is spoken at school.
Translation is offered in both languages for the general meeting when all members join together.
This is America. I am just glad that classes which involve more in-depth gospel study are offered in Japanese. Asako is from Akita and served a mission for the Church of Jesus Christ of Latter-day Saints in Hokkaido before coming to America in 1977. When the oldest two were in public schools in Central Utah, they weren't very interested in speaking Japanese at home. The children didn't have an opportunity to speak Japanese outside the home until the family moved to Salt Lake City in 1985 and started attending the Dai-Ichi ward.
