Message:

For nearly 20 years in China, Indonesia, and Myanmar, I have worked with numerous clients across government, private sector, and global professional firms. During this period, Japanese companies expanded globally rapidly, and countries once considered developing nations and aid recipients have emerged as rising economies and key business partners or clients for Japan. Not only are they becoming more prominent as inbound tourists, but they are also increasingly visible as investors in Japan. This renewed interest from Western investors highlights a remarkable transformation from, the perspective of my long-experience in Asia.

When people, goods, and capital move across borders, tax issues inevitably arise. Often, tax risks can escalate beyond expectations, making the understanding, assessment, and governance of tax risks a critical issue for management. As global business becomes ever more complex, the need for tax professionals who understand international tax practice and work closely with clients is only growing.

I am honored to contribute to JTA Tax Corporation, a new venture with a strong purpose, and I am committed to supporting the growth and success of our clients’ businesses.
