This museum is themed around salmon. The museum's name, Iyoboya, apparently means salmon in the Murakami dialect.
While it features various exhibits on salmon ecology, the history of salmon fishing, and fishing tools, the main attraction is probably the huge observation space where you can view the riverbed of the Tanegawa River, a tributary of the nearby Miomote River, through glass.
During salmon spawning season, you might even be able to witness the spawning process.
However, outside of the salmon migration season, you can only see small fish swimming in the slightly murky river...
There are also areas where you can interact with fish, making it a generally enjoyable facility.
Japan's first salmon museum.
After walking through a long underground passage, you can view a natural river from below the water's surface—a truly innovative design. It was quite interesting.
This facility offers a deeper understanding of Murakami's salmon culture and salmon itself. Admission is 600 yen per adult, and cashless payment methods such as PayPay are accepted.
"Iyoboya" apparently means salmon in the Murakami dialect. The facility has floors B1 to 3F, but it's a bit old-fashioned and the stairs are steep. There is an elevator, so it is somewhat barrier-free. On B1, you can directly see the riverbed of a tributary of the Miomote River via an underground passage, and apparently you might even be able to observe salmon spawning around November. This aspect reminded me of the Chitose Salmon Aquarium in New Chitose, Hokkaido.
The 1st and 2nd floors are exhibition areas. The focus is mainly on history and culture. There's only a little bit about salmon ecology. I think the New Chitose Aquarium is more interesting in that regard.
There's an observation deck on the 3rd floor, but it's a bit underwhelming.
There's a large, free parking lot in front of the facility. It's probably crowded during the high season around November. It's about a 15-minute walk from the tourist parking lot at Murakami City Hall.
