Episode 11 - Journalism of Hope

Release Date: 2020-05-16

Nowadays, there is a movement called "Constructive Journalism" occurring worldwide, in which citizens and the media gather information to solve local issues and everyday problems. In the United States, the distrust caused by highly sensationalized and speed-focused news, as well as the weakening of local media outlets, has led to a series of regional media companies going bankrupt. American media companies have crossed boundaries to collaborate and provide investigation reports to verify national and state policies. In Denmark, a public radio station has broadcast their citizens' worries as well as their solutions, and has grown to the point where it has influenced national policies. Similarly, in Japan, local newspapers have cooperated with each other to thoroughly address their readers' questions and worries, and have succeeded in solving national issues from a regional perspective. This is a documentary on the frontlines focusing on "Democracy in the Age of the Internet." (Excerpt)

Episode 15 - Peace and Justice: The Spirit of Japan's Postwar Constitution

Release Date: 2020-07-24

The coronavirus crisis has pushed many to the brink of poverty. A lifeline has been provided by Article 25 of the Japanese Constitution—the "right to existence," a guarantee of a minimum livelihood, modeled after Germany's Weimar Constitution. Scholars have recently begun to reassess Suzuki Yoshio's key role, who studied the Weimar Constitution before World War II and encouraged Japan to adopt the right to existence early in the postwar era. In the 1930's, Suzuki became a lawyer and defended numerous intellectuals who were facing political repression. After the war, he was elected to the House of Representatives, where he worked to incorporate newly emerging ideas from around the world into Japan's postwar constitution—the right to existence of Article 25, the pacifist stance of Article 9 and other provisions. Interviews and dramatic recreations based on the archival record tell the untold story behind the birth of Japan's constitution. (Excerpt)
