Hotaruika Museum, Marine biology museum in Namerikawa, Japan.
The Hotaruika Museum is a marine biology museum in Namerikawa, focused on the firefly squid and its natural environment in Toyama Bay. It houses aquariums, interactive displays, and informational exhibits covering the biology of these creatures and other marine life from the bay.
The museum opened in 1998 as an effort by Namerikawa to document and share knowledge about the firefly squid population of Toyama Bay. The city had long been a center for firefly squid fishing, and the museum was built to reflect that role.
The museum is closely tied to the local fishing tradition of Namerikawa, where catching firefly squid has long been a seasonal activity. Visitors can see traditional nets and tools, as well as displays showing how the squid is prepared and eaten in the region today.
The museum sits inside Wave Park in Namerikawa and is easy to reach on foot from the nearby train station. Visitors should plan for enough time to go through both the aquarium sections and the exhibit areas at a comfortable pace.
The firefly squid produces its own light through a process called bioluminescence, with tiny light-producing organs covering its body. During the spring season, the museum displays live specimens, allowing visitors to observe this glow up close in a way that is rarely possible outside of the open ocean.
