Matsuyama luggage hold / storage

Hello, I'll have some hours to spare in Matsuyama and would like to do some sightseeing, but I'm not sure whether I'll be able to find some kind of luggage storage anywhere (maybe with the dimensions, since my suitcase is quite big)
Thanks if you know anything

Hi, there are coin lockers at Matsuyama station. When you enter the station it is on the left side (anyhow the station is not that big so you should find easily. The price is between 300 yen per day for small to 700 yen for big ones.

Thank you for your kind answer

You can check the locker's dimensions and use on this page:

The small lockers are (nearly) always 300 yen, the medium and big ones can be more (up to 700 yen for the big ones).

Please enjoy your trip !
