The Great Tohoku Earthquake struck the north-eastern coast of Japan just two years ago, and brought with it tsunamis that took lives and destroyed countless homes along the coastline.

To this day, there are an estimated 315,000 people living in temporary housing as a result of natural and man-made disasters that occured after the quake.

As this is the two-year anniversary of this catastrophic event, we're spending the entire week highlighting presentations from the PechaKucha x ArchiAid Channel

In his presentation -- from the special PechaKucha x ArchiAid fundraiser -- Yoshiharu Tsukamoto (of Japanese architecture firm Atelier Bow-Wow) speaks of his efforts to build small, easily-expanded houses using the "Itakura Method" of construction to not only revitalize life on the Tohoku coastline, but to stimulate the surrounding forestry industry. Easy assembly, disassembly, and transport are among the additional benefits of the Itakura technique.

The original, Japanese version of this presentation (from Tokyo Desiger's Week) can be found here.
