Daiki Kasai

Daiki Kasai

Managing Partner

Fourteen years in Japan spent relentlessly tackling the work before me, even when the path ahead was unclear. Then came my overseas assignment, starting from a staff position. Looking back, I can say with confidence that every one of my more than 30 years of hands on accounting and tax experience in Japan and the United States has shaped who I am today. Drawing on this foundation and the latest expertise, we are committed to delivering practical, results driven solutions for Japanese companies and to serving as a trusted partner to our clients. At the same time, we remain dedicated to empowering our young professionals as they pursue their own growth and embody a strong spirit of teamwork.

Strategic Advisory Partner

With 30+ years of experience, I’ve guided companies through financial crises, COVID, and market shifts that test leadership. At Premier Kaikei, we bridge Japanese and U.S. business cultures to deliver solutions that honor both sides. We are not just accountants—we provide M&A, board, and recruiting support with empathy and foresight. Our mission is simple: create lasting win-win outcomes, not just short-term fixes.

In contrast to Japan’s relatively stable tax regime, U.S. tax laws are designed as dynamic policy tools—encouraging capital investment, innovation, and R&D, while also moderating excessive or misaligned growth. These constantly evolving rules can significantly accelerate business expansion and profitability when applied strategically. We advise clients on how U.S. tax laws impact their specific circumstances, translating complexity into practical, actionable solutions that support sustainable growth.

Senior Manager

When Japanese companies establish or expand their presence in the United States, they face a wide spectrum of challenges—regulatory differences, unfamiliar accounting and tax frameworks, and subtle yet consequential cultural nuances. Our role is to break down these complexities with care and precision, enabling our clients to operate with clarity and confidence.
In a time of heightened uncertainty, we are committed to providing solutions that are not only technically sound but truly actionable—across accounting, tax, finance, and M&A. Our goal is to ensure that every challenge becomes an opportunity, and every strategic decision leads to meaningful progress.
More importantly, we strive to be more than technical advisors. We aim to be a trusted partner who shares in our clients’ aspirations, helps shape their long-term vision, and stands alongside them as they grow. Our clients’ success is our greatest pride, and supporting each step of that journey is at the heart of everything we do.

Tatsuya Usui

Senior Manager

With 26 years of experience in external and internal audits as well as controller roles in both Japan and the United States, I bring a balanced perspective that bridges hands-on practice and management. My experience conducting on-site audits of subsidiaries worldwide, combined with 20 years of living and working in the U.S., provides a global mindset that distinguishes me from many firms. Rather than simply identifying issues, I work closely with clients to develop practical, actionable solutions. As a “hands-on, partner-oriented CPA,” I support the sustainable growth of global enterprises.
