Japanese version of AMP Fest 2020 event page contains untranslated English text

[rajucreate]

Description

While browsing the Japanese version of the AMP Fest 2020 event page, I noticed that a large portion of the content is still displayed in English even though the language is set to JA. The language switcher updates the URL and navigation correctly, but the main headings and page text don’t change.

Reproduction Steps

URL

https://amp.dev/ja/events/amp-fest-2020

Steps to Reproduce

1. Open the page above
2. Ensure language is set to JA (Japanese)
3. Observe page content

Expected Behavior

All visible text should appear in Japanese when JA locale is selected.

Actual Behavior

Large portions of text (e.g., "Rewatch the talks", event descriptions, section headings)
remain in English even on the Japanese version.

Tested Environments

• Browser: Brave (stable)
• Also tested in Incognito mode — same result

As I understood, this issue isn’t related to the amphtml repo. It belongs to the amp.dev repo, since the untranslated text is part of the website content rather than the runtime. Please reopen this issue in ampproject/amp.dev.
