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.
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.
On March 15, 2025, I spent an hour visiting the museum. It is the first salmon museum in Japan, and its name uses "Iyoboya," which means salmon in Murakami. Inside the museum, while salted salmon are hanging, visitors can learn about the ecology of salmon, fishing methods, the salmon culture of Murakami, and the life and achievements of Takeheiji Aoto, a samurai of the Murakami domain who devised the world's first natural hatching and farming method using seed rivers. At the back of the facility, there is a tank where you can look into the river and see salmon swimming in the river when in season.
In the ecological observation room, we saw salmon fry. Being fry, they were quite small and quick.
Iyoboya means "fish of fish," apparently.
There was also an observation window where you could directly observe the seed stream of the Miomote River, but unfortunately, the water was murky and we couldn't see anything... I guess that's unavoidable in March.
Real salted salmon were hanging everywhere!
The salmon skin blazer made from salmon skin was amazing!
Even the arrows in the corners of the stairs were salmon-themed. These little details are so fun.
I only intended to stop by briefly, but ended up staying for over an hour.
It was fun!
