日本の鉄道が禁煙ですか？
Non-smoking areas are becoming increasingly common in Japan, in homes, offices, restaurants, fast-food eateries, "family restaurants," pachinko parlors, and public areas. Kanagawa Prefecture enacted Japan's first smoke-free public places ordinance in 2009 and Hyogo Prefecture followed with a similar law in 2012. All trains either have non-smoking cars or are completely smoking-free, as are many train station platforms in urban areas.
