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!
We travel directly and flexibly to the Nagoya, Kobe, and Tokyo areas, and warmly welcome clients nationwide online.
We want to change the idea that "tax accountants are hard to approach." That is the spirit in which this office was founded.
Kubota Accounting & Tax Office goes beyond simple bookkeeping and tax filing. We value standing beside each business owner's vision and explaining the meaning behind the numbers in plain language.
"There's too much jargon, I don't understand," "I don't know when to reach out for advice" — we want to remove those worries and be a presence you can talk to anytime, with ease. Our mission is to walk alongside local sole proprietors and small-to-medium businesses, supporting their sustainable growth.
We explain things from your point of view, without jargon.
We use cloud accounting to deliver speedy, accurate processing.
We stay by your side for the long run — not just filings, but business advice and future planning too.
We provide thorough support from a professional standpoint. Centered on auditing and tax advisory services, we handle everything from business startup to fundraising and tax audit preparation.
We respond quickly to the statutory audits required of medical corporations above a certain size, as well as voluntary audits to support M&A, business succession, and stronger governance.
We handle corporate and income tax filings, as well as inheritance tax and various other consultations. With an efficient, PC-based environment, we won't keep you waiting thanks to outstanding speed and responsiveness.
We support you from preparing the filing documents needed to start a business or incorporate, through to building your funding plan and accounting system. For areas that fall under the exclusive scope of other licensed professions and that we are not authorized to handle, we will introduce you to our partner specialists.
Based on your monthly financial figures, we provide concrete advice on cash flow and profit improvement.
We support you from preparing application documents for startup and public loan programs through to negotiating with financial institutions.
We provide information on various subsidies and grants, and support you through application document preparation and submission.
We provide consistent support for tax audits, from advance preparation to attending on the day and handling communication with the tax office.
We provide consultation on international tax matters, including reporting of overseas assets, foreign tax credits, and tax issues related to cross-border transactions.
We mainly visit the Nagoya, Kobe, and Tokyo areas directly, and also support clients nationwide online.
For foreign entrepreneurs looking to start a company in Japan, we provide consistent support — from preparing the documents needed to incorporate, through to building your funding plan and accounting system. We also explain Japan's tax and social insurance systems clearly, without jargon.
Clients who have worked with Kubota Accounting & Tax Office have given us high praise time and again.
When my father passed away, I knew nothing about inheritance tax and reached out for help. Responses were fast, and every point was handled carefully while taking my wishes into account — I was able to leave it all in his hands with peace of mind. He's very easy to talk to and a trustworthy advisor who genuinely looks out for you. If I know anyone searching for an inheritance tax accountant, I'd recommend him without hesitation.
He handled our bookkeeping outsourcing. Very approachable, and he answered every question of ours carefully, which put us at ease. Responses were extremely fast and communication was smooth, which we really appreciated. Beyond just the work itself, he shared useful knowledge and advice that was a great help. A truly trustworthy tax accountant — we'd love to work with him again.
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 helped us with company incorporation. Everything was new to us and we were anxious, but he explained each step carefully, which let us move forward with real peace of mind. The process went smoothly, and he responded to our questions quickly and kindly — we're truly grateful.
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 understand he can also handle fundraising negotiations with financial institutions and drafting business plans. A tax accountant I can confidently recommend to anyone considering incorporation.
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'd love to ask him again next year if I have the chance.
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.
