Frequently Asked Questions
Can I buy an ad slot directly without crowdfunding?
Yes! Crowdfunding is optional. Browse our ad spots at /en/ads, pick a location and dates, then book and pay online — no Japanese required. English inquiries are always welcome if you want help choosing the right spot.
Do I need to be in Japan to participate?
No. You can book an ad or support a project from anywhere in the world, and pay by card. The ad itself is displayed in Japan — and if you visit, stopping by your own billboard makes an unforgettable photo spot on your trip.
What if the fundraising goal is not met?
All contributions are 100% refunded automatically if a project does not reach its goal by the deadline. You will never lose your money.
Who handles the permissions and design rules?
We do. Fan ads in Japan require media screening, and many artists' agencies or labels require prior permission. Our team runs those checks and makes sure your design meets each location's rules, so your ad clears review the first time.
What kind of ads can be placed?
Train station billboard posters, digital signage (LED displays), and large outdoor displays at locations across Tokyo, Osaka, and other major Japanese cities — including fan-favorite spots like Shibuya, Shinjuku, and Shin-Okubo.
Is there English support?
Yes. You can browse, book, and pay in English, and our team responds to inquiries in English. Feel free to reach out via the contact form anytime.
