Japan is finally slowing getting more smoke conscience little by little. In that vain I saw this book today. It's 235 no smoking restaurants and cafes in Tokyo, Yokohama and Kamakura. 235 may sound like a lot but there are probably 235 restaurants with in 15 minutes walk of my house and there are certainly thousands in most major parts of Tokyo like Shinjuku, Harajuku, Shibuya, Ebisu, Roppongi etc. Still, it's good to know if you need a break from the smoke there's more than just Starbucks.
