Masunosushi Honpo Minamoto (Toyama Station)

Minamoto's Masunosushi Honpo counter inside JR Toyama Station is the most accessible outlet of a shop founded in 1908 alongside the station itself, and it remains the most recognizable name in masuzushi, Toyama's signature pressed trout sushi. The product is built from thin fillets of trout cured and pressed with vinegared rice into a round wooden mold, then wrapped in bamboo leaf, a preservation method developed before refrigerated transport that gave rise to its enduring popularity as a portable regional food and train-journey meal. The standard ichiju masuzushi is a single-layer round meant for one or two people, while the tokusen premium selection uses higher-grade trout and a more generous cut; bamboo-leaf wrapped gift boxes are popular for bringing masuzushi home as a souvenir, since the vinegared rice keeps well unrefrigerated for a day. There is no dining room in the traditional sense; this is a walk-up counter and shop built into the station concourse, designed for grab-and-go purchases rather than seated dining, and there is no reservation system or wait beyond a short queue during peak train-transfer hours. The atmosphere is brisk and transactional, closer to a well-run bakery counter than a restaurant, and most customers are travelers buying a meal to eat on the shinkansen or a gift box to carry home. Because Minamoto is the most famous of Toyama's several masuzushi makers, it is often the first name visitors are given when asking where to try the dish, though comparing it against smaller family-run competitors like Takayoshi is a common pastime among repeat visitors to the city.
