Jujutsu

It's practiced by tens of millions around the world but there's no doubt that judo's spiritual home is Japan, where the martial art was created and made its Olympic debut.

It will be among the sports most closely watched by home fans at the pandemic-delayed Tokyo Games, and is so deeply embedded in Japanese society it even has its own branch of medicine.

The Glyfada Archdiocese released a statement that maintains that martial arts sports based on Eastern philosophy are a spiritual threat to Christians. The message came following the introduction of jiu-jitsu lessons at a number of primary schools of Greece.
