After graduating from university, Takeshi joined PwC Consulting LLC, where he worked on organizational and business process reform projects for government agencies and electronics manufacturers. He then moved to a real estate company, where he was involved in launching new businesses and managing a Japanese language school that accepted international students. While traveling throughout Asia to recruit students, he strongly felt the potential of Southeast Asia and the importance of its relationship with Japan, leading him to start his own business. He established a company that supported Japanese companies entering the Thai market and operated a rental office. Subsequently, he launched Monstarlab's Thailand office and its coworking space business. Including his previous role, Takeshi has supported over 400 companies in entering Thailand and launching new businesses there.
