The work environment and atmosphere are torture. Seriously, it is not a surprise that people commit suicide as much as they do (oh yes they really do). This isn't a problem specific to Sony HQ of course, many Japanese companies suffer from this. But honestly, the office space is cramped, dark, messy, overcrowded, outdated and very bleak. Hard to stay positive some days!
The "salaryman" salaries are low in Japan. Seriously, nothing compared to EU or US.
Plus there are no benefits - seriously, nothing. No discounts on PS (or Sony products), no freebies, no launch parties, no Xmas parties (well, we get a 2 hour bingo session with a few drinks and snacks), no training to non-Japanese, no off-site team-building...we even pay individually when our manager calls for a team meal & drinks in the evening. You get your salary, you get your bonus and that's it.
Very little chance for career development. Japanese people work for years and years until they are "the right age" just to finally get promoted to team leader of manager. There is very little internal movement opportunities for non-Japanese. 8 months ago I contacted HR to express my interest in broadening my career by moving to a new team or at least hearing of any internal opportunities, after a brief response confirming that they understood my request I never heard from them again.
Toilets- there are 26 floors and each floor has about 300+ people (mostly men), yet there are just 9 cubicles on each floor. People actually queue up and wait outside the cubicles.
There's a clock-in / clock-out system. You know how you see in old movies of factory workers punching their cards in and out? Well, now its digital but basically the same. And if you are not making core hours for the month then you are forced to use your annual holiday. Seriously, I missed core hours by 1 minute once - yes, just 1 minute - and I was told by HR that I must use half a day holiday.
