Founder & CEO, Sazae Pty Ltd – IT Consulting & SIer Operations in Australia, Japan, and Vietnam

After graduating from university, I began my career at an IT company in Osaka, where I was involved in system development and server operations. Since 2009, I have been based in Sydney, working with startups across various industries, including coupon services, mobile payment applications, legal tech, and edtech. I have contributed to global IT projects as an engineer and a manager, collaborating with teams in Japan, Australia, and beyond.

Currently, I serve as the Founder and CEO of Sazae, a company specialising in IT consulting, system development, and implementation of overseas SaaS solutions(ServiceNow, Boomi, Mendix, Odoo & Hubspot …) across Australia, Japan, and Vietnam. I am also the Co-founder of Innovation Dojo, which focuses on nurturing entrepreneurial talent, startup incubation, innovation-driven business development, and fundraising support.

In addition, I founded JAIT (Japan Australia IT) to foster communication and connection among IT professionals. We organise events in multiple countries to promote knowledge-sharing and community building.

I am deeply passionate about integrating IT and business to enhance client operations. I am committed to contributing to Japan’s global development and empowering Japanese individuals to succeed internationally.
