JP Ad Law Compliance Checker — AdLegalCheck

■ What is AdLegalCheck?

AdLegalCheck is a Chrome extension that automatically highlights Japanese advertising law violations — Keihyo-ho (景表法), Yakki-ho (薬機法), and Stema (ステマ) regulations — in real time while you browse EC sites and landing pages.

■ Problems it solves

• Worrying whether "No.1" or "cheapest" claims violate Keihyo-ho
• Tedious manual checks for Yakki-ho violations on health supplement pages
• Risk of missing unlabeled sponsored content under the 2023 stealth marketing regulation
• No way to save evidence of compliance checks

■ How to use (3 steps)

1. Navigate to any EC site or landing page
2. Click the toolbar icon → auto-scan begins
3. Violations highlighted in 3 colors, side panel shows risk score breakdown

■ What gets checked

✅ Keihyo-ho (misleading quality): "best quality," "world's first," "patented"
✅ Keihyo-ho (misleading advantage): "cheapest," "limited time only," "today only"
✅ Yakki-ho: "cures," "medically proven," "has effects"
✅ Stema regulation: "personal opinion" without disclosure, missing PR labels
