I found it by chance on my way back from a hot spring near the shop. The sign is big and eye-catching, so you can spot it at a glance even from far away. I was surprised to hear it was an unmanned gyoza shop. Inside, just as you'd imagine, there are vending machines. Besides that, inside there's information about gyoza and explanations of how to buy, written in big letters that catch your eye. It seems to be open 24 hours with no days off, so it's nice that you can go buy anytime. The gyoza were decently tasty too. If you're someone who likes exploring gyoza, I'd really encourage you to stop by.

Cash only. Opening hours have changed to 9-18!

It was delicious. I thought it'd be even better if the sauce were free 😅 I'd like to use it again!
