Subject: Feature Request: Full Japanese localization across Proton apps

Dear Proton Team,

Thank you for the excellent work on privacy-focused products. I am a long-time user and a strong supporter of your mission.

I would like to request full Japanese language support (localization) across your applications. While some services such as Proton Mail, Proton VPN, and Proton Pass already offer Japanese, several others do not yet provide a Japanese user interface. Specifically, I have noticed that the following appear to lack Japanese UI support:

Proton Calendar
Proton Drive
Proton Docs
Proton Sheets
Proton Meet
Lumo (chat content works in Japanese, but the interface itself is not localized)
As a Japanese-speaking user, having a consistent Japanese interface across the entire Proton ecosystem would greatly improve usability and make it easier to recommend Proton to others in Japan. Given that Japan has a large and growing audience concerned about privacy, expanding localization would also help Proton grow its user base here.

I understand that localization takes time and resources. However, I would appreciate it if Japanese support could be prioritized for the applications listed above.

Thank you for your consideration.

Best regards, TAKADA
