Profile
I am Yusuke Yokoyama.
I am a Tax Accountant.
Based on my experience and knowledge, I can help you solve your money problems including tax and enjoy your life more freely.
After graduating from university, I started working for a mega-bank, where I was engaged in sales of financial products, mortgage loans, apartment loans, and business loans and examinations, meeting the needs of people who want to increase and protect their money.
I then moved to the Tokyo Regional Taxation Bureau, where I was engaged in tax audits. After engaging in corporate tax and consumption tax examinations at the tax office, I was transferred to the Regional Taxation Bureau, where I experienced the examinations of many foreign corporations, among other things.
Based on these experiences, I started my own business in 2025 as a licensed tax accountant providing total support regarding money and taxes.
I would like to increase the number of people who enjoy their lives freely without financial worries by providing financial support, including taxation, to those who request it.

What I can do

English-speaking (Foreigners doing business in Japan often have problems with taxation. I can provide you necessary explanations about tax issues that are difficult to understand even in Japanese.)
Tax audit support services
I handle all aspects of tax audits for corporations and sole proprietors, including communication with the tax office, scheduling coordination, pre-audit consultations, on-site attendance during the audit, and follow-up procedures.
If you apply for this service, all subsequent communication with the tax office will be handled through me, so you will not need to deal directly with the tax office.
Communication between clients and tax accountant is typically conducted via email.
I also handle the preparation of amended tax returns.
Fees will be determined based on the number of days required for the initial on-site examinations, as follows:
【Price list】
| Plan | Price（Including tax） | Notes |

| Two days | ￥550,000 | |
| Three days | ￥770,000 | |
| ※More than four days, by TRTB examinations etc. | Estimate | I will provide an estimate based on the number of days and the scope of the examination. |

- Each plan includes all fees for the pre-audit consultation, scheduling coordination with the tax office, attendance on the audit day, and post-audit communication and negotiations with the tax office, as well as preparation of amended returns (corporate tax, income tax, consumption tax). However, if additional work such as data aggregation is required, it will be billed at ¥22,000 per hour and charged separately.
