Tiny houses are homes that occupy around 50 square meters of land. They're appearing more and more in recent years, especially in crowded cities. Many of them feature unusual layouts and creative design. Our guest, architect Sugiura Denso, introduces clever techniques that are used to make the most of limited space. We follow the construction process from start to finish. And we take a look at low-cost prefabricated tiny houses, measuring as little as 12 square meters.

Plastic food samples are astonishingly accurate replicas of real dishes. They can be found at the entrance to restaurants across Japan, helping potential customers to choose where to eat.

He also tells us why they became so popular in Japan, and discusses their presence in other countries.
