【Message】

A life worth living, in my opinion, is one that sets creative goals and boldly takes risks and challenges. Such a life is 100 times more valuable than a life that chooses only stability and safety. I started from scratch and went through storms in a much smaller boat and turned it into a giant ship. I have been through many disasters and hardships. Because I have gone through such a process, I have advice that I can offer, and I would like to be of help to future young people who have dreams of supporting Japan in the future.
