7th Store in Iwate Prefecture, First in Oshu City

As of today, six Matsuya stores are operating within Iwate Prefecture. With the opening of Oshu Mizusawa Store, the prefecture will move to a 7-store lineup, marking Matsuya’s first entry into Oshu City.

Area	Existing Stores
Morioka City	Morioka Ekimae-dori Store (0676), Morioka Odori Store (0698), Morioka Aiina Store (1734), Across Plaza Morioka Store (2054, co-located with Matsunoya), Morioka Mitake Store (2230, co-located with Matsunoya)
Ichinoseki City	Ichinoseki Store (2039, co-located with Matsunoya)
Oshu City (this store)	Oshu Mizusawa Store (2275, co-located with Matsunoya)

Matsuya’s presence in Iwate Prefecture currently totals six stores — five in Morioka City and one in Ichinoseki City — geographically concentrated in Morioka, with Oshu City remaining unentered despite being one of the prefecture’s major inland cities. With the addition of Oshu Mizusawa Store, Matsuya now has a presence across Morioka City, Ichinoseki City, and Oshu City, the prefecture’s major inland cities.

Matsunoya Co-location Status Within Iwate Prefecture

Within Iwate Prefecture, Matsuya/Matsunoya co-located stores will reach four locations with the addition of Oshu Mizusawa Store — launched as a co-located store from opening day — joining the existing three (Ichinoseki Store, Across Plaza Morioka Store, Morioka Mitake Store). This means four of the prefecture’s seven stores will be Matsunoya co-located locations, putting the co-location rate within Iwate Prefecture at roughly 57%.

Unlike the wave of Matsunoya co-location renovations at existing stores that has been running in parallel since April, Oshu Mizusawa Store follows the pattern of a new store launched as a Matsunoya co-located location from opening day. The most recent case of this pattern was “Matsuya Gozenmachi Oike Store” (2290) in Nakagyo Ward, Kyoto City, which opened on June 2, 2026, also as a co-located store from opening day — Oshu Mizusawa Store follows in that same pattern.
