Japan's "Day Service Las Vegas" operates 21 senior care centres with a casino-themed environment where elderly participants play card games and poker using casino-style chips (Vegas Coins) with no real money wagering. Survey data shows 93% of participants report increased happiness, and 80%+ show improved physical and cognitive performance after 2+ years; the operator has tracked 5,000+ seniors since 2015 with zero documented gambling addiction cases. The model reframes elder care from a necessity into an attractive destination, while reducing staff burden and attracting younger workers to the sector.
