世界最小水族館, Public aquarium in Chōshi, Japan

The World's Smallest Aquarium is a public facility in Choshi featuring an exceptionally compact design that displays marine species in specialized tanks. The exhibition uses the available space efficiently to present a range of local marine organisms while providing detailed information about regional sea life.

The facility opened in 2019 following the closure of the former Inubosaki Marine Park, marking a fresh start for Choshi's marine exhibitions. It built upon the knowledge and experience from the previous aquarium to create a new, more compact venue.

The facility displays marine species from local waters in its compact tanks, allowing visitors to see fish and creatures that live in the nearby ocean. The focus on regional sea life connects people directly to their coastal environment.

The location is easy to find, as it sits centrally in Choshi with signage to guide visitors. The visit is straightforward and typically takes only a short time because of the facility's compact size.

The facility operates in connection with a marine research laboratory conducting active scientific studies on site. This ongoing research work sets it apart from typical exhibition spaces and lets visitors witness marine science in action.
