Chester Tax Corporation (Headquarters: Chuo-ku, Tokyo; Representative Employees: Masaaki Fukudome, Yoshihiro Aramaki; hereinafter "Chester"), a tax accounting firm specializing in inheritance tax, is pleased to announce the opening of its "Tsukuba Office" in Tsukuba City, Ibaraki Prefecture, in April 2026. This expansion brings Chester's nationwide presence to 19 locations.
Background of Nationwide Expansion
In addition to Japan's aging society, the revision of the tax system in FY2015, which lowered the "basic deduction amount," has increased the number of individuals requiring inheritance tax filing procedures. Furthermore, in FY2023, tax reforms related to "lifetime gifts" and "vacant homes" were announced, making inheritance planning and inheritance tax filing more complex. We feel that the demand for tax accountants with specialized knowledge in inheritance tax is growing. Chester, which started from its Tokyo head office, now has over 400 employees, including group companies, and is a growing firm currently expanding to 19 locations nationwide. Moving forward, we aim to become the overwhelming No. 1 tax accounting firm specializing in inheritance tax, by continuing to expand into regions with demand, along with the growth of our employees, to assist as many people as possible with their inheritance needs.
