A friend moved to Japan to start a small business. His first task was straightforward: open a corporate bank account. What followed was the kind of bureaucratic experience that makes you question every life decision that led you here.
Opening a corporate bank account in Japan as a foreign founder is genuinely harder than it looks, and it has gotten harder recently. Regulations tightened in late 2025, with stricter requirements around capital and residency. This is what we found out.
Why the big banks say no
The major banks, SMBC, MUFG, Mizuho, are the obvious first choice. Established names, trusted institutions. But for a new foreign-led business they present an immediate problem: they are not just looking at your finances. They are assessing your long-term legitimacy and stability, and they have very little appetite for uncertainty.
Processing typically takes at least a month. They will ask for extensive documentation and multiple interviews. And the most frustrating part: if they reject you, they won't tell you why. No explanation, no feedback, no way to fix the issue for next time. You just don't hear back. That silence is the cost of Japan's extremely cautious banking culture, built around anti-money laundering measures and deep institutional conservatism.
If you want to try the major banks anyway, the best approach is to bring someone fluent in Japanese, ideally an accountant or professional advisor, to the appointment. Their presence signals legitimacy and seriousness in a way that's hard to replicate otherwise.
"A month of waiting and then silence. No reason, no feedback, nothing to fix."
What said yes
GMO Aozora Net Bank. Entirely online, designed for businesses, and genuinely fast. While traditional banks take a month or more, GMO can open a corporate account in a single day. In the Japanese banking environment, that speed alone feels like a miracle.
It integrates well with most major e-commerce platforms, which makes it practical for anyone running an online business. The main limitation is that it has no physical branch and doesn't handle direct inbound foreign currency payments. But that's not a dealbreaker.
Other online banks in the same category worth trying: Rakuten Bank, Sumishin SBI Net Bank, and PayPay Bank. All are digital-first, easier to open than the major banks, and practical for domestic e-commerce. PayPay Bank integrates particularly well with the PayPay payment system if that's relevant to your market. The limitation across all of them is similar: limited or no direct inbound foreign currency handling.
For handling inbound international payments, Wise is the most commonly used option but it's not the only one. Airwallex is worth considering if you're managing higher transaction volumes and want a more comprehensive platform with payment processing built in. Payoneer works well if you're selling on marketplaces like Amazon or Etsy. WorldFirst is another solid option, particularly for businesses moving money between Japan and other countries. Each has slightly different fee structures and currency support, so it's worth comparing based on where your customers actually are.
The other option is worth knowing about
There are also intermediary services, often run by foreigners, that handle everything end-to-end. Opening a bank account, submitting your yearly tax filing, managing the paperwork. If Japanese isn't your first language, this is worth considering seriously. Without strong Japanese the major banks become even harder to navigate, and having someone who knows the system handle it for you removes a lot of friction.
The tradeoff is cost. Because they sit in the middle, you pay more than going direct. But for most foreign founders who are new to Japan, the time and stress saved is often worth it. Just make sure whoever you use is reputable. Ask for referrals from other founders in the same situation before committing to anyone.
How to approach it practically
Honestly, still worth trying the big bank first. SMBC, MUFG, Mizuho. They're reputable, they offer broader services, and you never know, they might say yes. Give it a shot before assuming the answer is no.
If that doesn't work out, Japan Post Bank is worth trying next. It tends to be more accessible than the major commercial banks and is a legitimate step up from going straight to an online option.
And if you're hitting a wall with both, GMO Aozora Net Bank is your practical answer. It works, it's fast, and it covers what most small e-commerce businesses actually need. Think of it as your backup plan that you'll probably end up grateful for.
You can always open a major bank account later once your company has an established track record, consistent revenue, and local tax history. Secure something that works now and upgrade when you have more ground under you.
