Hakkeijima Sea Paradise Yokohama Guide 2026
Overview
Introduction: An Island of Marine Entertainment
Sea Paradise opened in 1993 on reclaimed land in Tokyo Bay. The concept was ambitious — build a complete marine leisure destination on its own island, combining state-of-the-art aquarium technology with amusement park rides and retail. Three decades later, it remains one of Yokohama’s most popular family destinations, drawing over 4 million visitors annually.

- Night operations: Summer evenings feature illuminated aquariums and night rides
Aqua Resorts (The Aquarium Complex)
The aquarium complex is the heart of Sea Paradise, comprising four distinct facilities spread across the island.
Aqua Museum
The centrepiece aquarium, housed in a distinctive pyramid-shaped building.
Main Tank:
- Capacity: 5,000 tons of water
- Species: Over 700 types of marine life
- Highlights: Giant groupers, rays, and schools of tuna circling overhead
- Viewing: Floor-to-ceiling windows plus an overhead tunnel section
Polar Bear Exhibit:
One of the few places in Japan where you can see polar bears. The exhibit includes both an underwater viewing window and an above-ground observation area, Feeding times (usually 11:00 and 14:00) draw the biggest crowds.
Sea Otter Pool:
The sea otters are a consistent crowd-pleaser, especially during feeding sessions when they float on their backs cracking shellfish against their chests.
Marine Mammal Arena (Dolphin Show):
| Show | Duration | Times (typical) |
|---|---|---|
| Dolphin & Sea Lion Show | 20 min | 11:00, 13:00, 15:00 |
| Dolphin Jump Performance | 15 min | 12:00, 14:30, 16:00 |
| Night Dolphin Show (seasonal) | 20 min | 18:00–19:00 (summer) |
Shows are included with the Aqua Resorts Pass. Arrive 15 minutes early for good seats — the arena fills up quickly on weekends.
Dolphin Fantasy
A tranquil walk-through aquarium where dolphins swim in a large, naturally lit tank. Visitors walk through a transparent tunnel while dolphins glide overhead, close enough to see the texture of their skin.
Best time to visit: Late afternoon (16:00–17:00) when the light from above creates beautiful patterns in the water. Weekday mornings are quietest.
Fureai Lagoon
An interactive touch pool area where visitors can:
- Touch bottlenose dolphins (guided sessions, ¥500 extra)
- Feed sea lions (¥300 per serving)
- Touch starfish and sea cucumbers (free, included with any aquarium pass)
Note: Dolphin touching sessions have limited capacity and sell out quickly. Register at the lagoon entrance as soon as you arrive.
UMI FARM
A hands-on fishing and cooking experience:
- Fish catching: Catch small fish from a shallow pool (¥500, 15 min)
- Cook and eat: Staff prepare your catch as tempura (¥300 extra)
- Seasonal activities: Net fishing, crab catching, sea creature exploration Good for children who want a more active experience than just looking.
Pleasure Land (Amusement Park)
Surf Coaster Leviathan
A roller coaster that runs partially over the water, with several moments where the track extends beyond the island’s edge. The feeling of speeding over open water with the bay stretching beneath you is the ride’s signature experience.

Blue Fall
A vertical drop tower — 35 metres of free fall. The seats rotate outward as you rise, so you face the ground during the drop. Not for the faint of heart.

Getting There
Best Time to Visit
Outdoor activities are best enjoyed in spring and autumn when temperatures are comfortable. Summer activities like swimming and surfing are popular from July to August. Some activities may close during winter months. Check operating schedules before planning your visit. Weekday mornings offer the best experience with fewer crowds.
What to Expect
Most activities are designed to be accessible for international visitors. Staff at popular attractions are accustomed to non-Japanese speakers and can communicate through basic English or translation apps. Duration varies from 1-2 hour experiences to half-day adventures. Wear appropriate clothing – many activities involve walking or standing for extended periods. Some outdoor activities may have age or height restrictions. Always check the official website before visiting for the latest information.
Local Tips
Regular participants recommend bringing your own water bottle and wearing moisture-wicking clothing for active experiences. Arriving 15 minutes before your scheduled time allows for check-in and preparation. Many activities have seasonal variations, so check what’s available during your visit. Don’t be shy about asking questions – instructors are happy to help.
Packing Essentials
For outdoor activities in Kanagawa, wear moisture-wicking clothing and comfortable closed-toe shoes. Sunscreen and a hat are essential during summer months. Bring a small towel for wiping sweat or for use at rest facilities. A waterproof phone pouch is useful for beach or water activities. Pack snacks and extra water for activities in remote areas where shops may be limited. A small first-aid kit with band-aids and pain relievers is always practical.
Money-Saving Tips
Save on activities by booking online in advance – many venues offer discounts for early purchase. Combination tickets covering multiple attractions often provide 15-25% savings. Visit during off-peak hours when some venues offer reduced rates. Check local tourist websites for digital coupons and promotional codes. Consider free alternatives like public gardens and observation decks that offer similar experiences to paid attractions.n
Conclusion
exploring Yokohama can be as relaxed or as packed as you want it to be, and I have found that the best visits leave room for both planning and spontaneity. During my visit to Yokohama I went with a rough plan and found that leaving room to wander made the trip far more memorable. Use this guide to sort out the logistics in advance, then let the day surprise you — Kanagawa rewards travelers who stay curious.
