Despite the global trend towards renewable energy, Japan's domestic efforts were greatly hampered by the after-effects of the Great East Japan Earthquake. While the country is behind where it would like to be, new advances in renewable energy are providing hope for Japan to get back on track. This episode will introduce 2 companies with very different ways of harnessing energy from the earth to generate electricity. One has developed wind turbines with a compact design that allows them to withstand typhoons. And the other has created unique waterwheels that are able to generate electricity from small streams and agricultural runoff.

In recent years the variety of sightseeing and tour options in Japan has started to climb almost as rapidly as the number of tourists visiting the country. Entrepreneurs are now coming up with creative and quirky offerings in order to compete for a share of this increasing market. One Japanese housewife has found success in the kitchen by opening-up her home to foreign visitors and offering cooking classes. Another tour that is climbing up the rankings is offered by a "pedestrian bridge" expert, who takes tourists on stair-climbing urban excursions.
