Non-electric coffee bean roaster made by Japanese engineers

Yasuyuki Fujimura is a non-electric studio built in Natsucho, Japan. In 1953, the world's first washing machine was introduced in Japan; in the same year, the national color TV standard was set. Since then, household appliances began to enter thousands of households, so 1953 is also known as the first year of electrification. The beginning of the electrification era marks the peak of human demand for energy. Nowadays, human beings have become dependent on electric energy.
