About Me
Administrative Scrivener
Tadatsugu Sakai
Rooted in the Community, Here to Support You
Profile
Hello, I’m Tadatsugu Sakai, a certified administrative scrivener. Before starting my practice, I spent about 16 years working in accounting, general affairs, and legal affairs in the manufacturing, trading, and real estate industries. Today, I work in my hometown of Matsudo, Chiba, supporting clients from Japan and abroad.
My strength comes from the practical experience I gained in companies—especially in improving efficiency and reducing costs. I want to support business owners and individuals who are taking on new challenges, so I focus on providing high‑quality services at fair and reasonable prices.
I always try to see things from the client’s perspective and offer sincere support that makes you feel, “I’m glad I came here.” With a reliable background in accounting, general affairs, and legal work, my goal is to be an approachable professional you can easily talk to whenever you need help. Please feel free to reach out anytime.
Hobbies / How I Spend My Days Off
I enjoy basketball, camping, and fishing, and I usually spend my days off outdoors. I also love traveling—both within Japan and overseas—and visiting new places is one of my greatest pleasures. Experiencing local culture, trying delicious food, and taking time to relax help me recharge and stay refreshed.
