15 Minutes Season 6

Two men have been called "the last ninja." The first is Fujita Seiko, who lived over a hundred years ago. Introducing himself as the last ninja, he held demonstrations throughout Japan and researched ninja arts. Going over footage of Fujita, we discuss the principles he taught. The second is Kawakami Jinichi, who is still alive today. We introduce the training he's continued for over sixty years and scientifically analyze a ninja breathing technique called "okinaga" to determine its effect.

We meet with two specialists at the forefront of ninja research. In 2021, Fukushima Takamasa found the Kanrinseiyo. Known to exist but never seen before, it's said to be the source material for the famous ninja manual, the Bansenshukai. It reveals previously unknown information about the ninja, including group tactics, night infiltration methods and a new ninja tool. We also learn about the ancient manuscripts Professor Yuji Yamada discovered at the Library of Congress in the US.

The Tokyo area is one of the most densely populated places on the planet.

We join architect Koshima Yusuke as he visits these tiny houses, and sees for himself the clever ideas that are used to create a cozy living space. This time, a house with an unusual living room—it hasn't got a roof!
