This article introduces how to adjust the default display language of GA4, such as changing the English interface to the Japanese interface. There are two ways:
Edit User Settings
In GA4, click 「Admin」——「My preferences」to see: 
After changing the Language setting, you must log out of GA4 and log back in for the new setting to take effect.
Adjust the URL Directly（Recommend）
There is also an easier way to modify the URL directly in the browser address bar.
The URL for the current report page is:
https://analytics.google.com/analytics/web/?hl=en#/p2499457200/reports/intelligenthome?params=_u..nav%3Dmaui
hl stands for Host Language，hl=en means the Host Language is English，modify the value of hl to change the actual language, such as hl=ja for Japanese. The modified url is:
https://analytics.google.com/analytics/web/?hl=ja#/p2499457200/reports/intelligenthome?params=_u..nav%3Dmaui
It is effective immediately, the language displayed on GA4 will become Japanese:
I recommend this approach.
