We build the story.

We buy the traction.

Janus Group K.K. is a venture studio and investment platform.

We build new ventures from the ground up and selectively invest in and acquire established businesses where we see a clear path to value creation.

We also advise founders and management teams on corporate development - spanning strategy, partnerships, and M&A execution.

We concentrate on sectors where customer experience, trust, and operational excellence matter most - business and consumer services. At the same time, we are theme-led rather than industry-limited. Beyond our core sectors, we will build, invest, and advise in other industries when we have conviction in the fundamentals, the team, and a well-defined value-creation plan.

What we do

  • Build - venture creation, brand, and go-to-market

  • Buy - investments and acquisitions with an owner-operator mindset

  • Advise - strategy, partnerships, and M&A

Janus Group K.K. is named after Janus, the Roman god of doors and transitions, looking both to the past and the future. It reflects our belief in building what is new and expanding what is proven.
