Body starts here
You want to do business in Japan.
You start researching, and almost immediately, you hit a wall. The legal system is complex. Business customs are unique. The language is a barrier. You don’t even know who to ask for help.
I spent 8 years at a Japanese trading company managing government ODA projects, working between Japan and the rest of the world. Now I work as a project consultant, helping individuals and companies enter the Japanese market.
From that experience, I can tell you this: doing business in Japan isn’t impossibly hard — but there are things you’ll regret not knowing.
Here are 5 things every foreigner should understand before starting.
1. Don’t try to understand Japan from the outside
There are plenty of reports and statistics about the Japanese market. But if you try to understand Japanese business through numbers alone, you’ll almost certainly get it wrong.
Japanese consumers are among the most quality-conscious in the world. This doesn’t show up in data. The texture of packaging, the politeness of service, the precision of delivery schedules — these invisible standards define the market.
That’s why it’s critical to talk to someone who’s actually in Japan before you enter the market. The gap between what reports tell you and what the ground reality looks like is far bigger than you’d expect.
2. Setting up a company is simple — but there are traps
Establishing a company in Japan is actually not that difficult. You can set up a KK (kabushiki kaisha) with as little as 1 yen in capital.
But there’s a catch most foreigners miss.
Visa issues. Even if you create a company, you can’t operate in Japan without the right visa. The Business Manager visa requires a business plan, a registered office, and several other conditions.
Bank accounts are another headache. Japanese banks are cautious with foreign-owned entities. Without a bank account, your business can’t function — so start this process early.
For these practical hurdles, having a trusted partner on the Japan side from the very beginning makes all the difference.
3. Learn to read the air
The biggest stumbling block in Japanese business is communication style.
In Japan, people rarely say “No” directly. “We’ll consider it” usually means a soft rejection. “That would be difficult” means it’s virtually impossible.
If you don’t understand this and push forward in negotiations, you’ll think everything is fine — until the deal suddenly goes silent.
The flip side: if you can navigate this culture, you’ll earn deep trust. Understanding what’s unsaid, building relationships patiently — that’s the key to success in Japan.
4. Translation alone won’t bridge the language gap
Google Translate and DeepL have gotten better, but machine translation alone isn’t enough for business.
Japanese has a unique structure where the level of politeness changes the entire dynamic of a relationship. A single email greeting can shape how you’re perceived. The way you hand over a business card, when you speak in a meeting, how you write a thank-you email — there are unspoken rules for everything.
What you need isn’t a translator. You need someone who understands Japanese business culture and can bridge not just the language, but the context. Someone who translates culture, not just words.
5. Trust takes time — but it’s worth it
In Western business, a signed contract starts the relationship. In Japan, trust comes first.
If you push for a contract in the first meeting, it usually doesn’t work. You meet, you talk, you share a meal, you exchange messages over weeks. Eventually, the other side feels “this person is trustworthy.” That’s when business begins.
It seems slow, but once you earn trust, Japanese partners are remarkably loyal. Long-term, stable relationships are the greatest advantage of the Japanese market.
