Not only does DIMENSION provide financial support through funding, we also aim to encourage significant business growth, based on the provision of our business growth knowledge and organizational development skills backed by our extensive IPO/M&A experience.

Since 2017 we are also publishing DIMENSION NOTE, featuring extensive interviews with noted entrepreneurs, who share their insights about business management. This is another way by which we share our growth strategies with the world and also provide input to our portfolio companies.

to market activation
through support for SDGs
and business development

The startups we fund and support are characterized by the following features:

  • Entrepreneurs and management teams that engage in management and business with serious commitment
  • Companies that have grown to reach a certain business scale and provide products and services that have the full support of society and customers
  • Companies providing new services that have the potential to become part of essential social infrastructure in the future

Rather than pursuing small IPOs and associated investment returns, our aim is to contribute to the SDGs and market activation by fostering entrepreneurs and socially significant businesses that will lead Japan in the future.



Building a society where people’s vision and commitment are rewarded


Always remembering mutual trust and respect


  1. 1. Moving forward with open communication

  2. 2. Always honest, sincere, and attentive

  3. 3. Execution leads to confidence

  4. 4. Self-evolution takes us further for longer on our journey

  5. 5. Just listen, imagine, and empathize

In order to realize our vision, DIMENSION places great value in not simply investing in startups, but also providing multifaceted management support to grow the businesses and organizational structures of the startups we fund.

In order to create value from this multifaceted management support, we must be a DEI organization—one that brings together a diverse group of talents, where each individual’s unique characteristics are fully utilized and everyone works seamlessly together as a team to create value.

DIMENSION is committed to building a corporate organization that values DEI, and to creating a team in which DEI is an intrinsic part of everything we do as we work to realize our vision.

Recognize and value individuals’ diverse backgrounds and specialties
Identify opportunities to ensure that people can harness their individual skills and evolve in a way that is best for them
Always pressing forward with mutual respect as we all look to realize our shared vision

We will always continue to build this DEI organization through our own efforts, and provide support for the realization of DEI organizations that best fit each of the startups we fund.
