Japanese Community Guide to Boston: Consulate, Groceries, Schools and Festivals

Boston’s Japanese community is small but well organized, with a consulate downtown, a Saturday school for children, specialty grocers in Brookline and Arlington, and one of the largest Japanese cultural festivals on the East Coast. This guide to Japanese life in Boston gathers verified addresses, population data from the U.S. Census Bureau and practical starting points for residents, students and newcomers from Japan.

How many Japanese residents live in Massachusetts?

According to the Census Bureau’s American Community Survey 2019-2023 five-year estimates (table B02015), about 9,429 Massachusetts residents (margin of error ±889) identify as Japanese alone. When people who report Japanese ancestry together with another race or Asian group are included, the count roughly doubles: the 2024 one-year estimate (table B02018) puts it at 21,038 (±2,951).

Within the city itself, the same five-year survey estimates 1,109 Japanese-alone residents in Boston (±316). The Census Bureau also tracks where immigrants were born. Its 2024 place-of-birth table (B05006) counts roughly 6,381 Japan-born residents statewide (±1,641), while the 2019-2023 five-year figure for Boston proper is 844 (±249). Many Japanese families live in suburbs such as Brookline, Arlington, Lexington and Cambridge rather than in the city, which helps explain the gap between the city and statewide numbers. Because these are survey estimates, the margins of error are wide for small groups.

Consulate General of Japan in Boston

The Consulate-General of Japan in Boston serves Massachusetts and the rest of New England. It handles passports, family registry (koseki) filings, certificates and visas. The office is at 100 High Street, 6th Floor, Boston, MA 02110, phone (617) 973-9772. It moved there on Oct. 20, 2020 from Federal Reserve Plaza at 600 Atlantic Avenue, so older directories still list the previous address. Consular services are generally by appointment, so check the website before visiting.

Japan Society of Boston and community groups

The Japan Society of Boston was founded in 1904 and describes itself as the first Japan Society in the United States. It runs cultural programs, business networking and language events, and lists Takeda, Japan Airlines and MUJI U.S.A. among its corporate members. For readers looking for broader Asian community services, our guide to Asian community resources in Boston, Quincy and Malden covers social-service agencies and advocacy groups.

Japanese language school for children

The Japanese Language School of Greater Boston (ボストン日本語学校) is a Saturday supplementary school, or hoshukō, that holds classes at Medford High School. It teaches Japanese language, math and social studies from kindergarten through high school, mainly for children who may return to Japanese schools, and it also offers a Japanese-as-a-second-language track open to children of any background. The Consulate’s education page lists other supplementary schools across New England.

Japan Festival Boston and cultural events

Japan Festival Boston took place on Boston Common on April 25 and 26, 2026, from 11 a.m. to 5 p.m., with a second stage at Summer Street Plaza near Downtown Crossing. Admission is free because Boston Common events must be open to the public. Organizers call it the largest Japanese festival on the East Coast. Dates for the 2027 festival had not been announced as of Oct. 23, 2026. The Japan Society and the Consulate post other events, including film screenings and cherry-blossom season gatherings, on their calendars.
