Narai Station, luggage storage

Does Narai Station have any sort of luggage storage (e.g., coin locker or other)?
I looked at the photos posted on google map, and none of the interior photo show coin lockers.

I did find one photo of a sign that reads "luggage storage service, 300 yen per bag per day",

, but I'm not sure if that is even taken at Narai Station (the sign is attached to a steel beam, but the station looks to be made of wood), or if the status is current.

One old post mentioned that the station is unmanned. So, how can there be a luggage storage service if it is unmanned?

Indeed, the station has no lockers, but the tourist information office inside the station offers storage at 300 yen per item, regardless of size. Opening hours: 9-16

I spoke with the tourist office a few days ago & was told you can store at the station for 300\.
However, I appreciate details provided by Uji as I couldn�ft communicate with the gentleman properly.

Another alternative is Shiojiri Station (east exit), 300\ too as per Shiojiri tourist office.

@ITO, would you mind returning here & let us know how you got on?
