The Olympic athletes' village turned homes: over ten thousand people on a reclaimed island with no railway station

Local guide

01First impressions

In January 2024, people started moving into the new buildings in Harumi 5-chome, an area that was originally the athletes' village for the 2020 Tokyo Olympics and is now called HARUMI FLAG. By August 2026, more than 11,000 people were already living here. There's no train station on the island itself — the nearest station, Kachidoki, is outside the neighborhood, and the furthest building is more than a 20-minute walk away. So getting around relies on buses and boats: the BRT (Bus Rapid Transit) takes about 11 minutes to Shimbashi, and a boat to Hinode on the opposite shore takes about 5 minutes. On the southwest side of the neighborhood is Harumi Wharf Park, facing Tokyo Port.

02What works

This park opened in 1975, closed during construction of the athletes' village, and reopened in October 2022. The ward-run Harumi Nishi Elementary School and Harumi Nishi Junior High School are right in the area, having opened in April 2024. Judging from our street photos, cleanliness ranks 3rd among Tokyo's 193 neighborhoods, and buildings rank 4th, both near the very top. But these two rankings need to be read alongside the photo dates in the next section.

03Heads-up

Most of these rating photos don't show how things look now: of the 148 rating photos across the 81 squares in the neighborhood, 77 were taken in 2022, when HARUMI FLAG was still under construction and no one had moved in yet. Only 16 were taken in 2026 — click on a square on the map to see the shooting date. As for transportation, public transit ranks 193rd among Tokyo's 193 neighborhoods, dead last. Convenience of daily life ranks 186th, also near the bottom.

04A bit of history

In 1931, this island, built up from seabed soil and sand, was completed; at the time it was called Tsukishima No. 4. In 1937, the public was invited to suggest a name, and it was named Harumi, in the hope that the sea here would always look clear and sunny. In 1958, Harumi Danchi was completed, and the following year the Tokyo International Trade Fair Grounds (a large exhibition hall) was built. The Tokyo Motor Show and Comic Market were both held here; after the venue closed in 1996, they moved to Tokyo Big Sight in Ariake. In 2000, the Oedo Line was extended to nearby Kachidoki, and the area around the old danchi was rebuilt into high-rise housing. In October 2020, Tokyo BRT began preparatory operations, and in January 2024, HARUMI FLAG began welcoming residents.

05What's coming

In Harumi 4-chome, a second school building for Harumi Nishi Elementary School is being prepared, which Chuo Ward plans to open in April 2029.

How are these measured?

Compared against the Tokyo neighborhoods in this guide; metrics without enough data are not ranked. Shopping counts convenience stores plus the nearer of a supermarket or a traditional market (public and private retail markets); night markets, vendor zones and shopping-street shops are not counted. Transit is rail-first with a lower weight for buses.
