When I first started out, I developed a strong foundation in accounting standards working for Andersen, KPMG, and Ernst and Young. I oversaw a general trading company and an electric power generation business that involved complex accounting procedures. At one point, I transferred to Mexico, where I gained practical experience in a foreign country, which differs from the standards of Japan and the United States. Over the years, I came up with the motto, "General Ledger = Bible." By understanding the company's current situation and looking at the financials in detail, I have learned how to prioritize, propose, develop, and implement sustainable and step-by-step improvement measures. We strive passionately to serve our customers with EOS, which allows us to flexibly respond to urgent issues that change daily with a sense of unity with our customers.
