Simple PAY.JP Payment for WordPress

I was setting up a small shop for a friend’s handmade goods in Kyoto, and needed something that just worked without a bunch of setup. I’d already tried a few WooCommerce gateways, but they were either overkill or didn’t support 3D Secure properly. That’s when I found this plugin. It’s not flashy, but it gets the job done - especially if you’re only dealing in yen and don’t need fancy reports or tax handling.

The good stuff

The shortcode thing is honestly nice. Just drop [payjp_payment] into a page, and boom - a clean payment form shows up. No backend wizardry. I liked how easy it was to set custom redirect URLs after success or failure. That saved me from having to hack around with PHP templates. Also, being able to hide the name field was a small win - my friend’s customers weren’t big on typing their full names during checkout.

And yeah, subscriptions work too. You give each plan a unique ID, which feels straightforward. If you’re selling digital downloads or monthly memberships, this handles it without needing a whole e-commerce suite. The plugin doesn’t try to do everything, and that’s actually refreshing.

The not-so-good

It’s not exactly *fun* to use if you’re outside Japan. The whole thing only supports JPY, so unless you’re targeting Japanese users, it’s useless. And there’s zero documentation. I had to dig through the code to figure out how the subscription IDs worked. Not a fan of that.

Also, the disclaimer about security is legit - they say you’re responsible for SSL and 3D Secure compatibility. But it’s not clear what happens if someone’s browser blocks 3D Secure due to settings. I’ve seen transactions fail silently because of that, and there’s no alert. A little more feedback would’ve helped.

And let’s be real - the developer is anonymous, license is unknown. That’s a red flag if you’re running anything serious. If you’re not careful, you could end up with a dead plugin that breaks mid-year.

Bottom line

If you’re a Japanese-based site owner needing simple JPY payments with minimal fuss, this plugin is worth a shot. It’s lightweight and does exactly what it says. But if you’re outside Japan, need multilingual support, or want actual customer support, skip it. There are better options out there. And yes, it’s free - but don’t assume that means safe or reliable. Use it with caution.
