What breaks when you travel on a data-only eSIM — checked country by country.

Japan · New account creation

Can you use Uber in Japan with a foreign phone number?

Likely, if you can receive a text.

Uber verifies sign-up by text to any number and doesn’t appear to require a Japanese one, so keeping your home SIM on for the code should be enough. That rests on Uber’s global help material, not a Japan-specific page.

Where this comes from

Uber global help centre plus consistent secondary write-ups. No Japan-specific policy page found.

How sure we are

This rests on consistent reports from travellers and guides, not on anything the company has published.

Next check
