Google Workspace vs Microsoft 365 in Japan

Start with the files, identities and relationships your business already depends on. Switching office suites changes more than email.

Test your important documents

Use real spreadsheets, presentations and shared documents in a trial. Check formatting, formulas, permissions and external collaboration. Include the accountant, client or supplier whose required file format is hardest to change.

Review account ownership

Confirm that the company controls its domain, billing and administrator accounts. Plan staff onboarding, account recovery and departures. Decide how shared files remain available when their original author leaves.

Compare complete plans

Check desktop applications, storage, security controls, meeting functions and support in the current business plans. Price the required users and add-ons. Avoid choosing from a feature that is available only on a higher tier than the one in your budget.

Migrate in stages

Inventory mailboxes and shared drives, test a small group, and schedule the cutover around business deadlines. Keep a rollback plan and verify mail delivery, calendars and file permissions before calling the migration complete.
