Building Disruptive Businesses Together


addlight is an innovation consultancy based in Tokyo, Japan. We combine strategy consulting, and a large network of startup and university contacts to build innovation within local and foreign corporations. We also work with foreign startups and accelerators to help local corporations gain advantages in Japan.


  • For Corporates

    We provide end-to-end and hands-on innovation consulting in Japan, connecting cutting edge Japanese startups and technology research from leading universities to build new businesses. Research reports on Japanese startups and technology trends are also available.

  • For Startups

    We provide startup acceleration services to help foreign startups grow from founding to expansion stages. We connect startups with local corporates for both long term projects and investment opportunities.


  • We produce a bilingual web magazine—addlight journal—covering the latest trends in next-wave technologies in Japan, the Asia-Pacific region, and further afield.
