Across the street from the Matsumoto JR train station is the Alpico Plaza department store (formerly Ario). It has a grocery store and souvenir section in the basement with a great selection of beer, wine and spirits. Alpico’s bus ticket office is also located on the first floor. On the top floor there are restaurants, an arcade and a 100-yen shop. Currently, the department store is under going renovation and will fully re-open in April 2018.
The building is directly connected to the Matsumoto Bus Terminal, so you can kill time walking around the shops or grab a snack while you wait for your bus.
