I thought that all that pride in their Katanas was invented and revisionistic after gunpowder came to Japan and they actually took way more pride in their skills with a bow.
If you bragged about your skills with a Katana in feudal Japan, you kind of admitted that your archery skills are shit.
Just to nit-pick, the Japanese never really figured out how to produce composite bows, the Yumi was just laminated bamboo. It was one of the reasons they couldn't successfully invade Korea until they were given western tech.
It's kinda ironic nowadays, but prior to the meiji restoration Japan was considered a cultural and technological backwater.
You have just been disavowed by the university of Tokyo for revising revisionism. You can't just go around attempting to dispel over 400 years of self aggrandizing, it's just rude.
