Hakkeijima Sea Paradise Tickets: Price, Which Pass to Buy and the Cheap Keikyu Ticket from Tokyo (2026)

Updated 2026-10-10

Short answer: walking onto the island is free. You pay only for the aquariums and the rides. For one adult (high school age counts as adult): the Aqua Resorts Pass for the 4 aquariums is ¥3,500, the Pleasure Land Pass for the rides is ¥3,500, and the One Day Pass for both is ¥5,900. Children under 4 are free. Coming from Tokyo for the aquariums, the Keikyu "Yokohama Hakkeijima Sea Paradise Kippu" is the best deal: ¥3,950 from Shinagawa for the train there and back plus the Aqua Resorts Pass, ¥1,230 less than buying them one by one, and it adds a ¥500 coupon.

Ticket prices

Sea Paradise has two paid parts: Aqua Resorts (4 aquariums: Aqua Museum, Dolphin Fantasy, Fureai Lagoon and Umi Farm) and Pleasure Land (rides). The island, the shops and the restaurants are free to enter.

• Under 4: free. Children aged 3 and under need no ticket but must be with someone aged 18 or over.
• The two night passes are sold only on weekends, national holidays and special days, and work from 16:00.
• A few rides are not covered by the ride passes (the "special amusements" such as the haunted house and the kids' land, which get a small discount instead).
• No refunds once you buy. The park's online tickets are sold through the Japanese site asoview!, which needs a free account.
• Ticket counters take Visa, Mastercard, JCB, AMEX and other cards, plus Suica, PASMO, Alipay and WeChat Pay.

Single ride prices

If you want only one or two rides, pay per ride at the Aqua Museum 1st floor ticket counter (or online):

Which ticket should you buy?

• Aquariums only: the Aqua Resorts Pass (¥3,500). Coming by Keikyu train, buy the Sea Paradise Kippu instead (below).
• Aquariums + 3 or more big rides: the One Day Pass (¥5,900). It costs ¥2,400 more than the Aqua Resorts Pass, and any 3 of Leviathan, Aqua Ride II, Sonic Tune and the Tower already cost ¥2,800 or more as single rides.
• Aquariums + 1 or 2 rides: Aqua Resorts Pass + single rides. Leviathan + Aqua Ride II = ¥2,200, still under the ¥2,400 gap.
• Rides only: the Pleasure Land Pass (¥3,500) pays off from about 4 rides. Leviathan + Aqua Ride II + the Tower = ¥3,000; add the Viking (¥600) and you pass ¥3,500.
• Arriving after 16:00 on a weekend or holiday: the night passes save ¥2,000 (One Day vs Rakuen Night) or ¥700 (aquariums only) per adult.

What it costs a family

Train fares are extra. For child train fares from Tokyo, see the Yokohama family train cost guide.

The Keikyu Sea Paradise Kippu: the cheapest way from Tokyo

Keikyu sells a 1-day set ticket, the "Yokohama Hakkeijima Sea Paradise Kippu", at the ticket machines of its stations. It has three parts:

1. a Keikyu round trip from your station to Kanazawa-Hakkei,
2. a Seaside Line 1-day ticket (the small automated train to Hakkeijima Station),
3. the Aqua Resorts Pass for the 4 aquariums, plus a ¥500 coupon for set shops on the island.

"Separately" uses paper-ticket fares; IC card fares are a few yen lower. The kippu is valid only on the day you buy it, and it is not sold at Sengakuji, the Haneda Airport stations or Kanazawa-Hakkei itself.

Want the rides too? Buy the kippu and add a Pleasure Land Pass on the island: ¥3,950 + ¥3,500 = ¥7,450 from Shinagawa. The One Day Pass with normal train tickets is ¥5,900 + ¥1,140 + ¥540 = ¥7,580. The kippu way is still ¥130 cheaper, and you keep the ¥500 coupon.

How to get there

• Station: Hakkeijima on the Seaside Line, an automated train along the coast.
• From Shinagawa or Yokohama (Keikyu): Keikyu Line to Kanazawa-Hakkei, then the Seaside Line to Hakkeijima (¥270, IC ¥265).
• From the JR Negishi Line: JR to Shin-Sugita, then the Seaside Line to Hakkeijima (¥320, IC ¥316).
• Direct bus: a limousine bus runs from Yokohama Station (YCAT) and the Minato Mirai area to the island, 2 trips a day.
• Cars cannot drive onto the island; parking is next to it (Lot A: ¥1,500 a day on weekdays, ¥2,000 on weekends and holidays). The park itself suggests trains on busy days.

To plan the rest of a Yokohama day, use our Yokohama day trip cost calculator and the Yokohama day trip itinerary. Sea Paradise is far from the harbour area (Minato Mirai and Chinatown), so plan it as a separate day rather than a stop on the harbour walk.

Hours and practical tips

• Open every day of the year, but hours change by date and season, and some rides close for maintenance. Check the park's hours page and ride closure calendar for your date before you go.
• Ticket sales start 15 minutes before the Aqua Museum opens. The aquarium times on the park's page are last entry; the buildings close 30 minutes later.
• Lockers: Center House 1st floor, next to the Aqua Museum entrance, and the passenger terminal. There is no bag storage desk.
• No ATM on the island. Bring a card or cash.
• Strollers can be rented through the Babycal service (book ahead): ¥250 for the first hour, then ¥100 per 30 minutes.
