Solving Tax Issues for English Speakers in Japan

I often get asked, “Why is tax incurred here?” Taxes are designed to apply when people live and engage in activities.

Management and inheritance issues bring complex tax problems. In today’s information-rich environment, I aim to connect your concerns and solutions seamlessly. The National Tax Agency provides little information in English, making it difficult for English speakers to get tax information.

With extensive experience in corporate roles, general affairs, and trade, I provide long-term support for solo entrepreneurs, freelancers, and small business owners. My expertise ensures a comprehensive understanding of the complexities of doing business in Japan, giving my clients confidence and security. I hope to be your trusted partner for consultation.

Representative / Certified tax accountant, MBA

Aki Kojima

Born in 1982, I live and work in Osaka City. After graduating from the College of Liberal Arts at International Christian University, I joined a trading company, sensing the potential of foreign markets. I worked as a development sales representative for new clients, importing and exporting chemical products, focusing on trade with India, China, and other Asian countries. While evaluating business partners in sales, I became interested in company management and switched to general affairs at a manufacturing company with businesses in the USA and Europe. I was in charge of accounting, labor relations, recruitment, trade practices, and IT management. During this time, I obtained my Certified Tax Accountant license. After that, I resigned and opened my tax consultant office. In my private life, I am a parent of two children. I enjoy photography, swimming, music, and manga/anime. I also update my blog regularly.
