Pro wrestling battles take place every evening in rings across Japan-over 150 pro wrestling events are held every month. Japanese pro wrestling was launched by the popularity of one wrestler: Rikidozan. 60 years ago, he drove the Japanese people wild, lifting the country's spirits after its demoralizing defeat in the Second World War. The Japanese have been hooked on this thrilling form of entertainment ever since. There are many "student pro wrestlers" in universities across Japan. Every March, they take part in an intense "Student Pro Wrestling Summit." There is currently a large number of pro wrestling organizations in Japan, each with its own niche. But some of these organizations struggle to make ends meet, and some wrestlers now also work outside the ring. On this edition of BEGIN Japanology, our theme is pro wrestling. We'll explore the appeal of this popular entertainment, which blurs the line between fantasy and reality.

Japan is the world's calculator superpower. Rivalries between Japanese companies to make calculators ever slimmer, lighter and cheaper eventually propelled Japan to the top, and Japanese manufacturers have led sales of calculators for over 30 years in many countries. Before the calculator came along, Japanese people did arithmetic on the abacus, and then used hand-cranked calculating machines. Even now, in the age of PCs and tablets, calculators are still essential in accounting jobs.
