I couldn’t verify a specific graduation date in March 2020 for Hiroshima Jogakuin University from the information available here. The university’s official pages surfaced in the search results, but none of the retrieved pages showed the March 2020 graduation ceremony date directly.

What I could confirm

  • Hiroshima Jogakuin University has official English and Japanese web pages available.
  • The search results I found did not include a March 2020 graduation announcement or ceremony notice for the university.

Best next step

The most likely place to confirm this would be the university’s archived news or announcements from March 2020, especially the graduation-related notices on the official site.
