The anti-smoking hysteria has not arrived in Japan yet, and smoking is still relatively popular. The smoking rate among adult men is almost 50%, while for women it is below 15%. The law prohibits the smoking of cigarettes to persons under the age of twenty. Cigarettes can be bought in tabacco stores and at vending machines.
If you are a sensitive person concerning smoke, you may have a hard time in some situations in Japan. Non-smoking areas are not very common in restaurants and public areas, not even in fast food or family restaurants. Furthermore, you won't be able to enjoy pachinko, since the parlors are extremely smoky places. On the other hand, all trains have non-smoking cars.
