  2. Open the official intranet/ESS address given by your employer.

!Can’t log in? Common fixes

  • Internal-only portals will not open from home without VPN — connect first.
  • Account inactive: new-hire access is typically enabled after HR/IT provisioning completes.
  • Expired corporate password: use IT self-service reset or contact the service desk.
  • Payslip/leave not showing usually reflects a payroll cycle, not a broken login.

✓Staying safe

IAUC Japan Auto Auction holds personal HR data. Use it only on the official employer domain, never save the password on personal devices, and report phishing that mimics the intranet login.
