Explore Toyama Bay’s deep sea through light and living creatures. Winter visits focus on luminous plankton and a deep-seawater touch pool. The experience differs from the live firefly-squid displays of spring.
What to see
- Watch luminous plankton in the winter live theatre; ask for show times on arrival.
- Learn how firefly squid live and produce light through films, LED demonstrations and exhibits.
- Observe the seasonal selection of Toyama Bay creatures in the deep-seawater touch pool.
