SIROK builds consumer brands from Tokyo.

As part of the CyberAgent Group, we launched N organic, a skincare brand now trusted by more than 3.5 million customers. In 2023, we followed with FAS, a skin longevity brand rooted in fermentation science. We develop, market, and sell our products ourselves.

One question guides our work: how many brands can we build that people will love for years to come?

We don't chase trends. We create services and products that keep earning people's trust, and we build and operate each one ourselves.

We find insights in people's everyday lives, including needs they have not yet put into words. We turn those insights into products, then use marketing to build lasting relationships between each brand and its customers.

We keep launching new ideas while giving each brand time to grow. We believe both matter.
