Oi Racecourse Flea Market: Tokyo’s Biggest (2026)

Tokyo · Shinagawa · Flea Market

By Nobu · Updated June 2026 · Verified against the organiser’s listings

On most weekends, the first parking lot at Ōi Racecourse fills with up to 700 stalls — Tokyo’s biggest flea market, where vintage clothing, antiques, cameras and household oddments change hands for pocket money from 9:00 to 14:30, and entry is free. It’s run by the Tokyo Recycle Movement Citizens’ Association, who hold more markets across the city, so on any given weekend there’s almost always one on somewhere.

What it is

Ōi Racecourse — the night-racing track in Shinagawa, also known as Tokyo City Keiba — rents out its first parking lot on non-race weekends, and the Tokyo Recycle Movement Citizens’ Association fills it with rows of stalls under the parking deck. With as many as 700 vendors it’s the largest regular flea market in Tokyo, and it’s mostly ordinary people clearing out their homes rather than professional dealers, which is exactly why the prices are low and the finds are unpredictable. There’s a food court if you need a break, and because much of it sits under the covered deck, light rain doesn’t shut it down.

2026 dates & hours

It runs on most Saturdays and Sundays, 9:00–14:30 — and you can actually get in to shop from 7:00 if you want first pick. The organiser’s official 2026 calendar runs January through September (October onward is posted separately on their Instagram). These are the 2026 dates from that calendar; still reconfirm on the official site or socials before you go, as heavy rain can cancel a day.

From November 2026 to mid-January 2027 the hours shift for the racecourse’s winter illuminations, so check those months carefully.

What you’ll find

It’s a treasure-hunt, not a tidy shop. On a given morning you’ll dig through vintage and second-hand clothing, old cameras and watches, ceramics and lacquer, leather bags, jewellery, vinyl records, kitchenware and boxes of small Showa-era curios and folk toys. Quality ranges from junk to genuine finds — the fun is in the rummage.

How to do it right

Other flea markets in Tokyo

If your weekend doesn’t line up with Ōi, the same organiser runs other big lot-markets nearby, and the wider Recycle Movement network it belongs to holds weekend flea markets at parks all over the city — so when you’re hunting for “a flea market in Tokyo this weekend,” there’s almost always one on. Always check the current calendar, as venues and dates rotate.

Getting there

Ōi Racecourse is its own stop: take the Tokyo Monorail from Hamamatsuchō (a few minutes from JR/Yamanote) to Ōikeibajō-mae Station — the market is about a five-minute walk away. It’s an easy add-on to a Tokyo bay-side day, or a first stop before Haneda since the monorail runs to the airport.
