It is 780 meters long, dead straight and has few distinguishing features, but the undersea pedestrian tunnel running 60 meters underneath the Kanmon Straits in southwestern Japan attracts a steady stream of visitors. Many people use the tunnel to travel between Fukuoka Pref. and Yamaguchi Pref., but others have different purposes in mind. The visitors are diverse: from a woman in her 20's who brought her boyfriend to the tunnel that is filled with childhood memories, a man who comes to secretly train for a marathon, to a woman who walks there every week with old friends no matter how busy she is. What draws them to this nondescript tunnel that remains unchanged, day after day? We spend 3 days looking at who walks through this underground passage.

Our stage this time is a remittance office in Okubo, Tokyo, where 40% of the population is international. Foreign workers visit this office in an endless stream, where money can be sent to 150 different countries for a fee of about 1,000 yen. An Indonesian woman sends tuition money for her sister's children, while a man from Africa transfers money to fly his son in to live with him. We listen to customers' stories as they send money, and love, to the people they hold dear.
