Four areas on the water
Odaiba is the name most people use for the whole bay area, but it is really four places. Daiba is the seaside part, with the Fuji TV building, a small Statue of Liberty replica, the artificial beach facing Rainbow Bridge and the malls Aqua City, Decks (home of the indoor Tokyo Joypolis) and DiverCity Tokyo Plaza, which has the Zepp DiverCity live house. The life-size Unicorn Gundam stood outside DiverCity from 2017 until its display ended at the end of August 2026.
Aomi, next door, has the science museum Miraikan (closed for renovation from October 2026 until spring 2027) and Toyota Arena Tokyo, opened in October 2025 on part of the old Palette Town site as the home of the Alvark Tokyo basketball team. Ariake is the convention and concert district: Tokyo Big Sight, Ariake Arena, Tokyo Garden Theater in the Ariake Garden complex, the Ariake Coliseum tennis stadium and the newer EX Theater Ariake. Toyosu, across the canal, has Toyosu Market, teamLab Planets, the Toyosu PIT live house and long waterfront parks.
Tokyo Big Sight and the conventions
Tokyo Big Sight, the building with upside-down pyramids, is Japan's largest convention centre. It hosts Comiket in summer and at the end of the year, Design Festa twice a year and a long run of trade fairs. Many trade fairs are for business visitors only, so check that an event is open to the public (ippan kokai, 一般公開) before you go.
Big fan events now mostly sell tickets or wristbands in advance, and the queues outside can be long and fully exposed. In summer there is little shade and the heat on the concrete is serious; in winter the wind off the bay is cold. Toilets and convenience stores near the halls get swamped, so arrive with water and snacks already in your bag.
- Bring cash in small notes for doujin and indie stalls. Many sellers cannot take cards.
- Coin lockers at the stations fill up early on big days. Travel light.
- On convention days, the first trains of the morning are already full of people heading to the same doors.
Arenas, halls and live houses
Ariake Arena and Toyota Arena Tokyo host big concerts, K-pop and sports. Tokyo Garden Theater is a tall, tiered hall where even the top seats feel close to the stage. Zepp DiverCity and Toyosu PIT are standing live houses, the kind where you pay a drink charge at the door on top of the ticket, often in cash. The Ariake Coliseum is the home of the Japan Open tennis tournament and also hosts other events.
The hard part is leaving. When a sold-out arena empties at 9pm, tens of thousands of people head for the same two small train lines. You can join the queue, have dinner nearby and leave an hour later, or walk to a less obvious station. From Ariake Arena, Kokusai-Tenjijo and Shinonome on the Rinkai Line are each about 17 minutes on foot, and their platforms are often calmer than the nearest Yurikamome stops.
- Top up your IC card before the show. The ticket machine queues after a concert are long.
- Check the last train before the encore. The Yurikamome and Rinkai lines are separate companies with their own timetables.
teamLab, the seaside and the seasons
teamLab Planets in Toyosu is a walk-through artwork where you go barefoot, wade through water that can reach your knees and lie in rooms of light and mirrors. Wear trousers you can roll up or shorts, and book a timed ticket ahead. The official run has been extended until the end of 2027.
Without an event, Odaiba is a good half day. Walk the beach at sunset with Rainbow Bridge and the city skyline across the water, then stay for the night view. Rainbow Bridge has a free walkway, a slow and windy way back towards Shibaura, which closes in bad weather. At Toyosu Market you can watch the morning auctions from the visitor galleries, and Senkyaku Banrai next door has food stalls and a hot spring.
In recent winters, Odaiba Rainbow Fireworks have lit up the bay on Saturday evenings in December, short shows of a few minutes that you can see from all along the seaside. Notices for events like this often say 雨天決行・荒天中止: it goes ahead in rain but is cancelled in a storm. In summer, big outdoor music, beer and food festivals take over temporary grounds in Aomi and the parks.
- The seaside is windy all year. Bring a layer even after a warm day, and a lot more in winter.
- Winter fireworks are short. Be in place a few minutes early or you will miss them.
Getting there and getting home
Two train lines serve the area. The Yurikamome is a driverless line from Shimbashi that loops over Rainbow Bridge and runs through Odaiba and Ariake to Toyosu; the front seats have the best view. The Rinkai Line runs from Osaki through Tokyo Teleport and Kokusai-Tenjijo to Shin-Kiba, and some trains run straight through from the JR Saikyo Line from Shibuya, Shinjuku and Ikebukuro. Toyosu is also on the Tokyo Metro Yurakucho Line, and Tokyo BRT buses run from central Tokyo out to Ariake.
For Tokyo Big Sight, use Kokusai-Tenjijo Station on the Rinkai Line, about seven minutes' walk, or Tokyo Big Sight Station on the Yurikamome, about three. Tokyo Garden Theater is a few minutes from Ariake Station on the Yurikamome. Ariake Arena is about eight minutes from Shin-Toyosu or Ariake-Tennis-no-Mori on the Yurikamome. Toyota Arena Tokyo is a few minutes from Aomi (Yurikamome) or Tokyo Teleport (Rinkai), and teamLab Planets sits right by Shin-Toyosu Station.
- The Yurikamome has small trains. On big event days it is often faster to walk a few extra minutes to a Rinkai Line station.
- Fares on both bay lines are higher than on JR, so a day pass can pay off if you hop around.
