Overview (history, characteristics, attractions)

Hekinan Seaside Aquarium is an aquarium located in Hekinan City, Aichi Prefecture, facing Mikawa Bay, that mainly exhibits marine life. It is characterized by its exhibits of creatures that live in the local ocean (tidal flats and coastal areas), hands-on programs for children, and its emphasis on learning and environmental education. Taking advantage of its location close to the sea, it is popular with families and school field trips, as it allows visitors to learn about the local nature and seasonal ecology. The aquarium is relatively compact and easy to see, and is designed to be enjoyed by people of all ages.

Highlights

  • Mikawa Bay Zone: Exhibits mainly feature fish, shellfish, and benthic organisms found in Mikawa Bay. Learn about the "ocean close to you" through regional exhibits.
  • Touch pool and seashore play area: An interactive exhibit where you can actually touch and observe starfish, hermit crabs, and other creatures (held depending on the season and time).
  • Exhibition tanks (medium to large): You can observe the behavior of the animals and the behavior of the schools through ecological exhibits and tank designs. There are often feeding times and explanations by the zookeepers.
  • Jellyfish and small creatures exhibit: A corner featuring creatures that you'll want to observe closely, such as jellyfish and small crustaceans.
  • Seasonal and special exhibitions: Special exhibitions on spring and summer creatures and environmental conservation, as well as events such as workshops and backstage tours are held (irregularly).
  • Seaside walks and outdoor spaces: The aquarium is also perfect for relaxing outdoors, as you can stroll along the coast and parks surrounding it.

Access (nearest station, transportation, etc.)

  • Public transportation: The nearest station is on the Meitetsu Mikawa Line (a station within Hekinan City), and it is common to take a bus or taxi from there. The travel time from the station varies depending on the mode of transportation, so please search for routes based on your departure point.

  • Relaxed: 2-3 hours (including a stroll around the nearby seaside park and lunch)

Things to be aware of (crowds, manners, seasonal precautions, etc.)

  • Crowds: The museum tends to be crowded on weekends, public holidays, and long school holidays (such as summer vacation). If you want to avoid the crowds, it's best to visit on a weekday morning.
  • Manners: There are rules regarding feeding and touching the exhibited creatures. Please follow the instructions posted in the museum and those of staff. Please be careful not to use flash photography or speak loudly, as this may disturb other visitors and the creatures.
  • What to wear and bring: If you're planning on using the touch pool, bring shoes and clothes you don't mind getting wet. If you're planning on walking around outside, don't forget to bring sunshades and drinks.
  • Safety: Keep an eye on small children, as areas near the beach and tidal pools can be slippery and dangerous.
  • Seasonal precautions: In summer, take precautions against the sun and heat, and in winter, there may be windy days and it may feel cold outside. In the event of typhoons or bad weather, the museum may be closed or events may be canceled, so please check official information in advance.
  • Check the latest information: Opening hours, closing days, admission fees, event information, and access details may change. Be sure to check the latest information on the official website or social media before visiting.

If necessary, we will refer to official information such as specific transfers and travel times from the nearest station, parking details, and information on ongoing events, and create a text that matches the latest data. Shall we look into this and reflect it?
