Nagaoka City Teradomari Aquarium Museum (長岡市寺泊水族博物館)

Flow of the course

About this spot

An old-fashioned, warm-feeling aquarium museum with a distinctive octagonal building projecting out into the sea. It displays about 300 species of aquatic life, centered on fish from the Sea of Japan. You can observe up close the very fish you just saw at the market swimming in the tanks. Feeding demonstrations by staff are popular, and the compact, child-eye-level museum layout is easy to navigate even with small children. The rooftop offers a sweeping panorama of the Sea of Japan.

Tips

The compact interior is easy to navigate with a stroller. Check the posted schedule for feeding demonstrations when you enter. On clear days, don't miss the view from the rooftop observation area.

Best time to visit

Allow about 1.5 hours. Early afternoon is less crowded with tour groups, offering a calm viewing experience
