1. Japan Mega Banks vs Japan Post Bank: The Day I Held My First Japanese Bankbook
When you first arrive in Japan and receive your residence card, everything suddenly feels real.
You’re officially here. But then reality hits you fast—you can’t really live without a bank account.
Rent, phone bills, part-time wages, salary payments—everything in Japan revolves around domestic bank transfers.
And if you’re a foreigner, you’ll quickly hear the rumors:
“Banks don’t like opening accounts for foreigners.”
“You need to live here for six months.”
“You must have a stamp, not a signature.”
I heard all of that too.
My first attempt was at Mizuho Bank.
The staff were polite, but firm.
“We’re sorry, but you haven’t been in Japan for six months yet.”
I walked out feeling completely lost—and ended up at the local post office instead.
That green sign marked the beginning of my financial life in Japan: Japan Post Bank, commonly known as Yucho Bank.
This guide is written so you don’t have to learn things the hard way like I did.
2. Japan Post Bank (Yucho): The First Door for Foreigners
Why Everyone Says “Start with Yucho”
Japan Post Bank is everywhere.
Not just in cities—even in rural towns where there’s no convenience store, there’s a post office.
For foreigners, Yucho is often the only realistic option right after arrival.
- No long residency history required
- No income required
- Very tolerant toward students, working holiday makers, and newcomers
That’s why people say: “Open Yucho first, think later.”
Strengths of Japan Post Bank
- Nationwide ATM coverage (the strongest in Japan)
- Long free ATM usage hours
- Easy account opening shortly after arrival
- Reliable for utilities and phone bill payments
As a cash storage and survival account, Yucho is unbeatable.
The Limits You’ll Eventually Feel
- Online banking UI feels outdated
- Low transfer limits
- High interbank transfer fees
- Some employers don’t allow Yucho as a salary account
👉 In short, Yucho is a starting point, not the finish line.
