Cumulative Samples for Gut Microbiome Testing Exceed 250,000!

Saikinso, a company with the corporate philosophy of 'improving human health through microbiomes' (Headquarters: Shibuya-ku, Tokyo; Representative Director: Yosuke Hara), announced that its cumulative sample count for the 'Mykinso' gut microbiome testing service surpassed 250,000 as of April 2026.

Saikinso pioneered the commercialization of gut microbiome testing for individuals in Japan in 2015 and has since expanded the 'Mykinso' series. With the increasing recognition of the importance of the gut environment for health maintenance, the number of samples reached 250,000 in just about nine months since surpassing 200,000 in July 2025, accelerating its growth.

The 250,000 samples represent one of the largest databases in Japan and globally. These data serve as crucial assets for unraveling the health conditions of the Japanese population across diverse lifestyles, significantly enhancing the value of data utilization in academic research and business settings.

The company has built a massive data foundation through consumer testing and solutions for enterprises and research institutions. Moving forward, it will leverage these data assets to develop businesses aimed at realizing a 'zero-order prevention society.'
