Kyoto's summers are famously hot, but if you take the Eizan Railway and get off at Yase-Hieizanguchi Station, you'll find a spot along the Takano river where you can cool off, enjoy a barbecue, or relax by the water with a drink and read. This spot is particularly recommended for those staying in Kyoto long-term rather than for short-term tourists.
This is a local liquor store that has been here since before I was born, offering not only alcohol but also rice, tobacco, and other daily necessities. The owner, who is always there in the mornings and afternoons, is a very friendly and wonderful person. You can buy and drink inside the store, and smoking is allowed as well. I often see people gathering to enjoy a drink, smoke, and have casual conversations with the owner. This kind of super-local, cozy atmosphere is one of my favorite things about the place.
If you have that famous I-see-faces-everywhere thing, look twice. The Face House really exists in Kyoto, created by Kazumasa Yamashita in 1973-1974.
Don't miss it - it's something really faceinating!
