Document 72 Hours - Season 1 (2013)

Every year, 16 million people pass through Sapporo's New Chitose Airport, on Japan's northernmost island of Hokkaido. In spring, many dramas of greeting and parting play out as people come and go between the great expanses of the north and the megalopolis of Tokyo to the south. A surprise sendoff for a friend leaving to go to school in Tokyo. Tears flowing at the first big family reunion in 20 years. A foreign student's dreams for the future. It is a season of major life transitions.

The Akihabara district in Tokyo is known worldwide as a mecca for "otaku" or geeks. It's also where a number of girl groups dance and sing. The otherwise obscure "live theaters" where they perform have become major new attractions for the groups' wildly enthusiastic fans. But for these underground idols, the showbiz life is rough. They don't earn much. Rival groups are forever a threat to displace them. How old can the girls get before they lose their appeal? Yet they do not easily abandon their dreams.
