About Hattori Law

Hattori Law is an international business law firm dedicated to providing legal services for cross-border transactions, foreign direct investment in Japan, as well as Japanese investment overseas.

We have successfully supported foreign companies investing in Japan in areas including cross-border business negotiations, regulatory compliance, real estate investment and the hospitality sector. Our international practice focuses on the cross-border legal needs of clients across a wide range of industries.

We recognise that clients establishing a business in Japan may face language barriers in a predominantly Japanese-speaking business environment, in addition to differences in business culture and legal systems. These challenges can make it difficult to run a business smoothly.

We help our clients navigate these challenges with respect for those differences – an approach we see as essential to bridging Japan and other countries in business. Through this approach, we aim to pave the way for our clients’ success in cross-border business.

Our approach also reflects an understanding that business decisions depend not only on the law but also on relationships with business partners and corporate policies. We bring legal insight to these considerations to help our clients make informed business decisions and manage legal risks.

In 2026, following our selection in 2025, we were once again honoured to be named as a finalist in the “Rising Law Firm of the Year” category at the ALB Japan Law Awards, organised by Asian Legal Business (ALB) of Thomson Reuters. Our founder and Managing Partner, Shingo Hattori, also served as a judge for the ALB Japan Law Awards from 2020 to 2023.

We do our best to be the right law firm for our clients.
