Waiting for a flight in transit at an airport is an unwelcome burden for travelers. But at Narita International Airport, that spare time could become a memorable part of the journey.

The Narita Transit Program offers tourists who have plenty of layover time before flying out of Japan a short tour to get a taste of the country's history and culture in the area around the airport.

Since starting up in March, it has gained popularity among overseas visitors passing through the airport.
