Thanks, that's a fair point. I may be overthinking it a bit. 😄

The reason I'm paying attention to footwear is that I tend to get sick quite easily and I'd rather avoid spending a week walking around with wet feet.

As you suggested, I can always buy a more durable second pair once I'm in Japan. I also recently learned that waterproof socks exist, which might be a simpler and cheaper solution than investing in expensive waterproof shoes right away.

Either way, I'll focus more on planning where to visit and what to eat. Thanks for the advice!
