Pro Tips

  1. 1.Purchase combination tickets online in advance for both the aquarium and amusement park areas to save money and skip ticket lines.
  2. 2.Arrive when doors open at 10:00 AM to experience the dolphin and whale shows with smaller crowds, as they fill up quickly in the afternoon.
  3. 3.Download a park map in English from the official website before visiting, as signage is primarily in Japanese.
  4. 4.Bring yen cash for food vendors and smaller shops, as not all locations accept credit cards.
  5. 5.The island is compact and walkable, but comfortable shoes are essential as you'll cover significant distance between the four aquarium buildings and attractions.

Best Time to Visit

Visit on weekday mornings (Monday through Thursday) when crowds are lighter and shows are easier to access. Avoid Japanese national holidays and summer weekends when the park gets extremely crowded. Spring (March to May) and fall (September to November) offer pleasant weather for outdoor exhibits.

What to Know

Combination tickets covering all aquariums and rides cost approximately 5,500 yen for adults and 3,900 yen for elementary students (aquarium-only passes available for less). The island has multiple restaurants and food stands, though kid-friendly Western options are limited. Some English signage exists, but a translation app is helpful.

Seasonal Notes

The park is open year-round with extended hours on weekends. Summer brings special evening illumination events and longer operating hours until 9:00 PM. Winter months (December to February) can be cold for outdoor shows, so dress warmly. Some outdoor rides may close during inclement weather.

Nearby Eats

The island itself has family-friendly restaurants including a food court with Japanese and Western options near the Aqua Museum. For more variety, Yokohama's Minato Mirai district (15 minutes away) offers numerous kid-friendly chains including ramen shops, conveyor belt sushi, and family restaurants with picture menus.
