They might as well be in the military with haircut requirements like that!
Price structure?? Try living in Japan bro. Everything is more expensive than you could ever imagine. The only way to get ahead here is to avoid paying taxes by working a 2nd job under the table. The transit system is high quality, low efficiency, and high price. Bullet trains are almost never full. Why? In some instances it is cheaper to take an airplane! In all case it's cheaper to take the slow, local train, but your ride will seriously be horrible if you are near a big city. This haircut thing is classic Japanese corporate behavior. Expend effort on something dubious that probably makes no difference when there are far better ways to save energy staring them right in the face. You think "HOW CAN A WHOLE COMPANY DO SOMETHING SO DUMB AND CRUEL?" But it is an anthill with one person making such decisions.A much smarter move would be to unplug all the toilet seat warmers that are left on 24 hours a day for 8 months out of the year. Oh and putting a little insulation and weather stripping on ... ANY building in Japan basically..... that would start to solve some of their glaring energy waste problems. The temperature here in Japan is almost always uncomfortable so people turn on their heater or A/C. Then... where does all that air go? It flies out the cracks around the doors and windows, and gets absorbed by the empty walls. EVERY SINGLE BUILDING IN JAPAN IS LIKE THIS.
