Japan's Indian community, estimated at approximately 55,000 by early 2026 -- historically centered in Kobe since the early 1900s and more recently concentrated in Tokyo's Nishikasai ('Little India') area following a post-1990s IT-sector boom -- relies on the OCI card, not dual citizenship, to maintain a lasting legal connection to India.
From Kobe's early traders to Tokyo's IT diaspora
Indian traders were recorded in Japan as early as 1901, with a community of several dozen established
in Hyogo Prefecture by 1905. The center of Japan's Indian community shifted from Yokohama to Kobe after
the 1923 Great Kanto earthquake devastated Yokohama's trading community, and Kobe's India Club
(originally the Oriental Club) was established in 1904 and remains a historic community landmark today.
A sharp, distinct wave of growth followed post-1990, as Japanese manufacturers brought in industrial
trainees and, increasingly, IT professionals settled in Tokyo's Setagaya and Minato wards. Tokyo's
Edogawa ward -- particularly the Nishikasai area, sometimes called “Little India” -- recorded
3,758 people of Indian ancestry in 2018, roughly 10% of the national Indian-origin population. Today the
community stands at approximately 55,000 Indian nationals per early-2026 estimates, with a further
healthcare/nursing recruitment pathway opened by a 2021 Japan-India specified-skilled-worker agreement.
Why OCI, not dual citizenship, is the relevant status for India
India does not permit dual citizenship for anyone, so a person of Indian origin who has taken up
Japanese citizenship cannot simultaneously hold Indian citizenship. An Overseas Citizen of India (OCI)
card is the applicable route to a lasting Indian legal status: OCI confers lifelong multiple-entry access
to India and parity with NRIs on several economic, financial, and educational matters, without conferring
voting rights, government employment eligibility, or the right to hold agricultural land.
Registering an OCI application from Japan
OCI applications from Japan are processed through the Embassy of India, Tokyo, or the Consulate
General of India in Osaka-Kobe (or online through the OCI portal, with the physical passport later
submitted for the sticker/booklet), following the same national OCI Rules that apply from any other
country, including the 2026 amendments that moved applications further online and clarified that a minor
cannot simultaneously hold both an Indian passport and a foreign passport.
Common mistakes made on this point:
- Assuming Japan's own naturalization rules mean India also permits dual citizenship for a person
of Indian origin who has taken Japanese citizenship -- India's law does not allow this.
- Confusing OCI with a visa -- OCI is a distinct, more durable status conferring lifelong
multiple-entry access, not a time-limited visa.
- Not renewing an OCI card's linked new passport details after a passport renewal, which can cause
travel document mismatches.
