Four of the five Casio watches released in Japan on August 7 are already listed below Casio's own pricing in the country. By the end of that same day, four of them were already listed below Casio's own prices at Japanese retail. One of the clearest cases is the Pro Trek PRJ-B001EX-1JR. Yodobashi, a national electronics chain rather than a marketplace reseller, has it at ¥26,400 against Casio's ¥33,000. That is not a grey-import price or a proxy markup, but a major Japanese retailer undercutting the manufacturer on release day.
