Magento 2 – How to Set Default Locale

localemagento2

In magento 2, how to set default locale? I default in admin page below:

I cleared all cache by command: magento cache:flush. But, it until get locale is en_US. If the true is ja_JP.

We need to create ja_JP.csv in your custom theme: app/design/frontend/{Vendor Theme}/{Theme name}/i18n/ja_JP.csv

We can find the locale code by simple way:

I see only one reason why this happens - incorrect locale was set in the configuration. Please check your configuration ("store view" scope):

In a debug I see that magento works fine.

Configuration (ja_JP):

Result (ja_JP as set):

First you need to find out the language code by using

php bin/magento info:language:list

Once you've found the language code you can set the language by calling

php bin/magento setup:store-config:set --language=code

UPD for v2.2

magento config:set general/locale/code ${LOCALE}

or:

magento config:set general/locale/code ${LOCALE} --scope=store --scope-code=${STORE_CODE}
