What to do at Nagano Station for 1 hour?

Hi, i will have one hour to spare at Nagano station in between changing from the Electric train to the Shinkansen. Will be with my medium sized trolley luggage, thus not planning to walk to Zenkoji Temple. Are there any nearby malls / cafes / restaurants that you recommend i check out? Thanks in advance.

Nagano station itself isn't too attractive. You might want to keep your luggage at the station and visit Zenkoji or perhaps visit the tourist information center (within the station) to ask for a nearby coffee joint.

You'll need more than an hour to see Zenkoji - but there is a large coffee joint out the front on the normal train entrance.

There is also some shopping - but there is not too much you can do at this station for an hour.

Station building of Nagano Station to open in March 7th.
However, if it opened in November of last year, it seems to have 46 shops open.
Coffee shop called the third floor of Maruyama coffee is open.
Second floor of Tully's also doing maybe.

Although the store was also good that Suyakame, walk and it takes 15 minutes one way.
I ate miso soft cream and grilled rice ball there.
