Quick answer: Dolphin Fantasy is in Yokohama, not Ito
Dolphin Fantasy is one of the aquarium areas at Yokohama Hakkeijima Sea Paradise in Kanazawa Ward, Yokohama. It is not the same place as dolphin facilities around Ito or Shimoda on the Izu Peninsula.
Choose Hakkeijima when you want a large, city-accessible marine leisure day with aquariums, rides, dining, and dolphin viewing. It is a captive-animal aquarium visit, not a wild dolphin swim or a boat wildlife tour.
- Location: Hakkeijima, Yokohama
- Dolphin Fantasy is part of the four-aquarium Aqua Resorts area
- Choose an aquarium-only or broader pass only after checking the selected date
- Do not expect a wild-dolphin encounter or swim
Which ticket fits the day?
Hakkeijima sells several pass types. The important decision is whether you want the four aquarium facilities only, or also want attraction rides. The official rate page identifies Aqua Museum, Dolphin Fantasy, Fureai Lagoon, and Umi Farm as the four aquarium facilities.
Klook currently lists aquarium and attraction ticket packages with date-specific availability. Treat the package shown for your selected day as the source of truth for entry, cancellation, inclusions, and any time restriction.
| Plan | Usually fits | Check before paying |
|---|---|---|
| Aquariums | Visitors focused on marine exhibits and Dolphin Fantasy | Which aquarium facilities and entry conditions are included |
| Aquariums plus attractions | A full-day family or mixed-age visit | Ride access, height rules, weather closures, and the actual date |
| Night or time-limited pass | Visitors with a short afternoon or evening window | Entry time and included facilities |
Getting there and planning realistically
The official access information and current Klook listing place Sea Paradise at Hakkeijima in Yokohama. Klook describes a walk from Hakkeijima Station on the Seaside Line; leave enough time for the station-to-island walk, bag checks or queues, and locating the ticket entry point.
Hours and programs vary seasonally. Do not plan around a particular animal presentation, ride, or exhibit without checking the official schedule for the actual date. Weather can affect outdoor attractions even when the aquarium portion remains the main reason for the trip.
- Check opening hours and last admission for the selected date
- Save the mobile voucher and carry a charged phone
- Allow an arrival buffer instead of scheduling a tight onward train
- Check attraction and show operations separately from admission
A responsible way to frame the visit
Dolphin Fantasy is an aquarium experience involving animals in human care. It should be chosen for the facility as described, not presented as a substitute for wild dolphin behavior or an open-sea encounter.
Follow the facility's current photography, crowd-flow, and animal-interaction rules. A calm, observant visit is more useful than treating animals as a guaranteed photo opportunity.
Planning note: seasons, prices, safety rules, schedules, and availability can change. Confirm the current details with the relevant operator before booking. Related language versions: ko zh-tw
