It should only affect users who authenticate with a username only, without a domain.
The only effect is to add the domain name to the username.
You could perhaps test, by logging in as just "user" and then as "user at example.co.jp" and make sure everything behaves the same.
If everything behaves the same, then setting auth_default_realm should not do any harm.
In other words, the question is: does any functionality actually depend on having a username without a domain.
