Many foreign tourists to Japan often question why public transportation, especially in areas of Tokyo renowned for their nightlife, is so limited after the last scheduled trains.

Amid the country's ongoing tourism boom, officials are brainstorming for ideas to address this dissatisfaction, and others, and boost tourists' spending by encouraging more nighttime outings to shows, restaurants and scenic spots in the country.

Some municipalities are proposing night markets in parks and DJ events featuring street vendors.
