Is poor work culture in Japan even after Masters in Engg

Hey everyone,
I'm currently at a crossroads in my academic journey and could really use some advice from those who’ve been through this or know more about it.

So a bit about me — I hold a diploma and a B.Tech in Mechanical Engineering (Automobile), and now I’m planning to pursue my Master’s abroad. I’ve narrowed it down to Japan and Germany.

Here’s the thing:
I’ve always had a serious admiration for Japanese car culture — the engineering, the heritage, the street scene, everything. That’s what initially drew me toward Japan for my Master’s. But lately, I’ve been hearing a lot from people — friends, seniors, even online posts — about poor work culture in Japan, especially things like long working hours, strict hierarchy, lack of work-life balance, and difficult integration into teams if you’re not fluent in Japanese or not Japanese at all.

These are mostly rumors and secondhand opinions, and I don't want to judge unfairly. But I’m genuinely in a dilemma now — should I go ahead with Japan (which I love in terms of culture and industry), or should I consider Germany, which seems more welcoming in terms of work-life balance and international exposure?

So my main question is:
If someone pursues a Master’s degree in Japan (especially in Mechanical or Automobile Engineering), how is the work culture for foreign graduates? Is it manageable or as harsh as some people say? Do things improve if you’re qualified and skilled?

Would love to hear personal experiences, insights, or even honest warnings from people who’ve studied or worked in Japan after their Master’s.

Thanks in advance
