Period: From April 14, 2026 (Tuesday) to around mid-May 2027

Notes
1. For the A.C.C.C Computer System Satellite, rooms A203 and A207 will be unavailable during the renovation period. Rooms B205 and B206 will be available for classes only.

• If you are using these rooms for classes, please note that the entry procedures have changed. Please refer to the provided documents ( japanese ) for details.
• Please use the restrooms in nearby facilities. The closest option is the International Lecture Building.

2. The A.C.C.C Office will be temporarily relocated to the 3rd floor of Building CA during the renovation period.

• Please refer to the documents ( japanese ) for the new location.
• Telephone numbers and email addresses will remain unchanged.

From early February 2026, when creating a new group in Teams, SharePoint, or Outlook (Microsoft 365 Groups), “-group” will be automatically appended to the end of that name.
This change is intended to prevent the creation of inappropriate names and to avoid confusion in management.

For example, new teams named “SpringAclass” and “PRteam-public” are changed to “SpringAclass-group” and “PRteam-public-group”, respectively.

Please be informed that existing teams or groups are not affected by this policy unless you rename the existing ones. Also please note that newly created “public” teams are required to have the suffix “-public” as announced before.

Any question please ask: https://www.cc.tsukuba.ac.jp/wp_e/contact/ees_inquiry/
