What are the best stores to buy a gi from?

I’m visiting Japan for the first time in less than 2 weeks – yippee! – and I wanted to know what are the best stores to buy a gi from. I’ve been doing jiujitsu for a while now and I figured I should buy a gi straight from Japan as one of the treats for myself. 🤭

For reference, I’ll be going to Kyoto, Osaka, Okinawa, and Tokyo.

Thank you in advance!
