T akanori Nakamura is a self-made Japanese technology billionaire and the founder, chairman, and CEO of Rakus Co., Ltd., a provider of cloud-based software services. After working as an engineer, he founded the company in 2000. Rakus has become a leader in the Software-as-a-Service (SaaS) market in Japan, catering specifically to the needs of small and medium-sized businesses (SMEs).

The company offers a suite of cloud-based software products that help businesses automate and streamline their back-office functions. Its flagship products include tools for expense management, payroll processing, and customer relationship management. Nakamura's strategy of focusing on the underserved SME market, which has traditionally been slower to adopt cloud technology, has been highly successful. The rapid growth of his publicly traded company has made him a key figure in Japan's burgeoning SaaS industry and a self-made billionaire.
