PROVIDING A COMFORTABLE BUSINESS ENVIRONMENT FOR GLOBAL CLIENT
PROVIDING A COMFORTABLE BUSINESS
ENVIRONMENT FOR GLOBAL CLIENT
Here at Otani & Partners, we always wonder how far the notorious principle “When in Rome, do as Romans do” should extend to international business
Ever since the company’s foundation, we’ve seen thousands of foreign business people struggling with tax and accounting issues, let alone being able to read the forms or get professional advice in English.
We are not conventional. We aim to be different. O&P has made its purpose to support foreigners to make them feel like they’re practicing in their home country.
We exist in Japan. For foreigners. By foreigners.
David Otani, Director of International Department



OUR STORY
Story begins
We have 40 years of experience in providing tax, accounting
and payroll services.
From a single office established in 1983,
we have grown into one of the leading accounting firms in Japan
which supports foreign businesses.
Otani & Partners has
found its niche, and we will continue to grow our business by
helping you grow yours.

1983
Establishment of the Japanese Office
Japanese Department paved the way for the humanity and sincerity
approach to doing our business. All types of clients matter.
Regardless of the business field and company size, we are always
eager to support our clients by providing efficient solutions for
their business.
The reason why we were able to proceed and grow
our business lies at the root of the company attitude towards
clients, which was initially developed together with the
establishment of the Japanese Office.

2013
Foundation of the Chinese Department
We started handling clients coming from mainland China, Taiwan,
Hong Kong, and Brazil.
Our founder’s knowledge of and experience
in International Political Science, which he studied in Taiwan,
enabled us to handle International Taxation in the early years of
its existence.
It has also become one reason we could aspire to
become English service providers to our clients.

2017
International Office Establishment
We became the first office to provide English service at an
average market price for foreign entrepreneurs.
This milestone
allowed our clients to enjoy the tax benefits and eliminate the
language barrier, thus ensuring compliance with the Japanese Tax
Regulation. After Covid-19, our service became popular among
foreign investors because of the relationship between service
quality and service price.
Our motto has been and will always be:
« High-quality service at a reasonable price. »

Today
Together towards common goal
We’ll dedicate all our knowledge, skills, and experience to build
and maintain the bridge between foreign clients and the Japanese
financial market.
We can do that because we share an ambition to
build a successful future with each and every client we work with.
We are your trusted partner, with a commitment to your business
that does not emanate from a desire for profits.
