Japan’s ageing population—tired of “childish, patronizing” activities—are embracing casino-style daycares.

In the past year alone, as many as 60 Las Vegas-style daycare facilities emerged in the country that cater to local retirees, Financial Times reported. There are at least 10 million Japanese residents aged over 80.

Today’s elderly crowd, according to businessman Kaoru Mori, are tired of staying home by themselves, but at the same time, the market didn’t want the “childish, patronizing” activities that the majority of about 40,000 adult daycare facilities in the country are offering.

Entrepreneurs saw the demand for “serious activities,” and gambling-themed establishments were born. Mori, who owns at least 10 similar centers, told FT he plans to open more across Japan.
