Hi Square community!
I’m using Checkout API to create the payment link, but my client wants to issue the payment page in Japanese.
I skimmed Checkout API document, but there were no topics for language setting.
Are there any ways to change the payment page based on the selected language?
Is the sellers Square account a Japanese Square account? If so the page will render in Japanese. 
Thank you for the reply.
Oh really? Yes. Japanese Square account.
When I request location API, country and language code are Japan/Japanese.
However, somehow preview of check out page shows in English. (I checked with Japanese browser setting, but the language was English. )
FYI
I was able to create Japanese payment page from the dashboard manually.
However, I issued Checkout page via Checkout API and that didn’t work.
What’s the language set on the device your using?
Did that change the language for you?
No,
I have been stacked to input the password. Neither my client or I didn’t set up the password.
What is the default password?
I found this topic.
I thought my problem came with English Sandbox test account, but we were not supposed to be changed the language setting from developer account?
If so, which language settings Checkout API referred to under the sandbox?
Okay. Now. I got the japanese page!
We needed to check production API for language settings. I guess we cannot see any changes on sandbox checkout page.
This includes allow_tipping option also.
Glad you got that sorted out, @ryounosuke! Let us know if there’s anything else we can help with.
