Shoes that you can slip on and off easily. Light clothes. When I was there two summers ago, it was rainy and cooler than any of my other trips, but I never wished that I had long pants. I'd risk leaving long pants at home, unless you have a tat you want to cover until you are actually inside of a sento/onsen, (when most establishments are too polite to ask you to leave!)
