About Me

"I consulted a specialist, but it was full of jargon and hard to understand..." I want to be the partner who takes that worry away.

Nice to meet you! I'm Jun Kubota, a Certified Public Accountant and Tax Accountant known as "Junior-High-Graduate Accountant Jun."

As the nickname suggests, I passed the CPA exam after leaving formal schooling at the junior-high level, and I currently teach bookkeeping as a professional instructor at a certification prep school. My greatest strengths are the solid, practical know-how built up as the third generation of a family of professionals since my grandfather's time, and clear, easy-to-understand explanations — a skill honed through years of teaching.

Have you ever consulted a specialist only to be met with jargon you couldn't follow? At our office, we walk alongside business owners and their families as a partner who breaks down and clears up every worry, however small.

Rather than a stiff, distant "sensei," I want to be someone you feel comfortable turning to with "let's just ask Jun." Our first consultation focuses above all on clarity, carefully helping you organize your current situation. However small the question, please feel free to reach out!

My practice is small, and while I could handle the calculations myself, I struggled with bookkeeping and tax filing — that's when I found this office. With regular monthly communication, he teaches us about accounting and tax matters, and it's a huge help to be able to ask anything at all. He also carefully lets us know what documents we'll need each month and around tax return/closing season, which makes preparation much easier.

He holds a CPA qualification, has experience at a major accounting firm, and has worked across multiple industries — so he really engaged with our needs and gave great advice. It was a huge help.

I'm a salaried employee with about ¥2 million in side income from FX trading, and asked him to handle my tax return. He's very approachable and easy to talk to, and even pointed out and handled things I had overlooked — I felt completely at ease leaving it to him.

I consulted him about unemployment insurance. He explained not just the basic system but also the details and steps needed to make sure I didn't lose out, going over it with me repeatedly. I get nervous easily, but he mixed in interesting, useful stories along the way and I was able to relax throughout the consultation. I'd like to recommend him to friends too. Thank you so much.

When my father passed away suddenly, I consulted him about inheritance tax. My father had run a company, and since this advisor is also a CPA, it was incredibly reassuring to have his help. He's very easy to talk to and a wonderful advisor who genuinely looks out for you. I plan to keep consulting him going forward, including for tax returns.
