Tax Advisory
Tax advisory & filing
Bookkeeping and in-house accounting support
We record your transactions based on the receipts and invoices you send us. If you want to bring accounting in-house, we show your staff how to use the accounting software, give advice suited to their level and follow up on their progress.
Tax advisory (tax questions and accounting reviews)
We explain tax questions and issues clearly and propose the best solution. If you do your own accounting, we check that it is correct and reflects how your business actually operates.
Annual tax returns
We estimate your year-end results early, plan accordingly, and prepare your corporate tax and consumption tax returns. We also prepare individual income tax returns for sole proprietors and people with income from property sales or side businesses.
Tax audit support
We support you from preparation and attendance on the day of the tax audit through follow-up with the tax office, presenting your position as a professional and easing the practical and emotional burden.

Startup Support
Starting a business in Japan
We support people starting a business or setting up a company. We compare sole proprietorship and incorporation, handle notifications to the tax office and other authorities, and help with funding plans and loan applications — guiding you through the key points and schedule at the start.

Cloud Accounting
Cloud accounting & going paperless
We help you move from paper receipts and invoices to cloud accounting and electronic records: setting up freee or Yayoi Accounting Online, linking bank accounts and credit cards, complying with Japan’s Electronic Bookkeeping Act and qualified invoice system, and using AI tools — with patient support even if you are not comfortable with systems.

Inheritance & Gift Tax
Inheritance & gift tax
We prepare Japanese inheritance tax and gift tax returns and advise on inheritance planning. Even when the estate includes assets that are hard to value, such as real estate or unlisted shares, we explain each step clearly. We also tell you which documents are needed, when to collect them and how to obtain them.

Consulting

Financial and tax due diligence to evaluate target companies and uncover potential risks, business valuation based on objective data, and reorganization support from structuring and tax simulations to project management.
Internal control
Drafting and reviewing internal rules, redesigning business processes for efficiency, and preparing the documentation required under J-SOX.
Business restructuring
For companies with declining performance, we identify financial issues and propose solutions, including business plans, cash flow forecasts and break-even analysis.

Audit
Audit
Having audited the financial statements of many listed companies and funds at a major audit firm and its overseas office, we perform audit procedures to the same standard. While we do not audit listed or large companies, we accept statutory audits of small companies under the Companies Act, audits of special purpose companies (SPCs) and public interest corporations, and voluntary audits of overseas subsidiaries.
To maintain independence, we may not be able to audit clients for whom we provide tax advisory or other ongoing services.

Other Services
Other services
Back-office outsourcing
For small companies, hiring accounting and administrative staff is costly and difficult, and a resignation can bring work to a halt. Outsourcing administration, including accounting, to specialists ensures stable, high-quality operations so you can focus on your business.
Outside corporate auditor
As an independent professional with experience as a corporate auditor of private companies and overseas subsidiaries, we serve as an outside corporate auditor covering both operational and accounting audits.
