Still, stay alert

No major threat indicators — but a clean scan does not guarantee every page is safe, and phishing emails routinely spoof real domains.

Double-check the exact URL in your address bar
Confirm you are actually on cpi.ad.jp and not a lookalike like c-pi.ad.jp.com or an IDN homoglyph.
Use a password manager
Password managers only auto-fill on the exact domain they were saved for — they refuse to fill lookalike domains, which is the single best phishing defence.
