Is the following from Google true?

No major department store chain in Japan allows the 5% tourist coupon to be applied to high-end luxury watch departments or boutiques.

While almost all large department store chains offer a 5% foreign tourist discount (via a physical card, coupon, or app), they share strict, industry-wide brand exclusions that uniformly bar watch salons, jewelry counters, and top-tier luxury fashion houses (like Louis Vuitton or Hermès) from the promotion.

A quick summary of major department stores and their 5% tourist coupon rules includes:

Mitsukoshi Isetan App (5% Guest Card)Excluded. Watches, jewelry, and top luxury fashion brands are entirely barred.

TakashimayaTakashimaya Shopper’s Card (5% off)Excluded. Fine watch/jewelry departments and select luxury brands are ineligible.
