Why Choose Japan Bonus
Verified Before Listed
We verify licences in regulator registers and read the operator's published withdrawal rules. If we can't confirm it from a primary source, it doesn't make the list.
Bonuses, Straight From the Source
Every offer listed here is one the casino itself publishes — we link straight to it and check the terms against the operator's own pages.
Built for Japanese Speakers
JPY support and Japanese-speaking customer service — the things that matter when you play in your own language.
FAQ
Frequently Asked Questions
How do I identify a safe online casino?
First thing — check the license. MGA (Malta) or Curacao are the ones you want to see. Then look for the padlock icon in your browser's address bar — that means SSL encryption is working. Every casino on our site has already passed these checks, so you're good to go if you pick from here.
What is a no deposit bonus?
It's basically free money (or free spins) you get just for signing up — no deposit needed. Great way to test a casino before committing your own cash. Just keep in mind there are usually wagering requirements before you can withdraw any winnings.
How long do withdrawals take?
Gambling can be addictive. Please play responsibly. 18+
