I'm a merchant who wants to communicate in 'Japanese' with my customers, what should I do?

Translation for Japanese is not available by default in Chargebee (see the complete list here), so you need to do the following:

• Contact support@chargebee.com to add Japanese to the list of languages for your site
• Upload the Language pack, with translation text in Japanese
• Enable the Japanese in the Settings > Configure Chargebee > Languages screen
