You're missing out on the most critical detail of Japanese culture that is lost by most westerners:
Speed isn't more important than having respect for your craft. If you have to go slower to produce a better result, you go slower. If you have to work harder to perfect an incredibly tight joint, you do that. You don't have to use traditional joinery to build in Japan today. But if you build something in a shitty way, it reflects poorly on you.

Efficiency is not the goal.
