A boutique consulting firm.

Gran Manibus is a boutique consulting firm under SCSK, one of Japan’s premier IT services companies, and Sumitomo Group, one of the largest Japanese trading companies.

Internationally-minded executive team

Both our president and vice-president come from international consulting companies, each having worked in them for more than 15 years before joining us. Our CTO previously worked at Microsoft’s US headquarters, before going on to establishing the Japanese subsidiary of Slalom, a Seattle based technology consulting firm.

This blend of Japanese business connections and international business methods puts us in a unique position to help our clients transform their business through technology.

Startup environment without the financial uncertainty

Our working environment is similar to that of a startup, but due to being part of the Sumitomo and SCSK Group, there is no risk of financial instability.

We already have a global network

Many Japanese companies aspire to go global, but fumble when taking the first step. We already have Sumitomo’s global network that we can leverage, and we’ll be able to tap into this as we expand outside of Japan.
