Japanese actor and singer Kobayashi Asahi spends tens of thousands of yen on health supplements to maintain his wellness [1].

The routine highlights a growing trend of celebrity-led wellness culture in Japan, where high-cost supplement regimens are often used to offset previous lifestyle habits.

Speaking at a press conference for his concert, “Kobayashi Asahi Concert ~Eien Fumetsu no Might Guy~,” the entertainer described a regimen involving about 40 different types of supplements [1], [2]. He said he rotates these products annually, typically using a specific supplement for about one year before stopping if he feels it is not working [1].

Kobayashi said the habit has become a personal fixture in his life, saying, "It has become a habit," in a translation from Japanese [1]. He said the significant financial commitment required for the routine, saying, "I spend hundreds of thousands of yen on supplements alone" [1].

The shift toward a supplement-heavy lifestyle follows a broader health overhaul for the performer. Kobayashi said he adopted these measures to maintain his health after he quit smoking and reduced his alcohol consumption [1], [3].

By rotating the products, Kobayashi aims to find the most effective combinations for his body. He said he repeats the cycle of trying a supplement and then stopping after a year if it lacks a noticeable effect [1].

“I spend hundreds of thousands of yen on supplements alone”

Kobayashi's approach reflects a common pattern in the Japanese health market, where consumers often treat supplements as a rotating trial-and-error system rather than a static prescription. His transition from smoking and drinking to a high-cost supplement regimen underscores the psychological shift toward 'wellness optimization' among aging entertainers in the public eye.
