What is the sense of duty which drives Yakuza gangs to murder?
A successful new crime drama, starring Japanese actors, includes scenes set in London and Tokyo.
At one stage, there’s a violent confrontation in a famous hotel, with lots of fighting and dead bodies.
The drama draws on the powerful idea of giri 義理 – a sense of duty or obligation which drives the members of yakuza gangs to murder.
In this week’s Japan Story blog, we hear how giri is also a concept which guides a man’s relationship with his mother-in-law.
