Mayumi Hongo

Ms. Hongo is a Partner at Atsumi & Sakai. She has the unique experience of working as a lawyer specializing in infrastructure after working for about 10 years for one of Japan's leading heavy industry manufacturers. She has long experience working on legal issues with project members at the forefront of the company, so she is able to be close to her clients as she aims to resolve issues from a practical point of view.
In recent years, Japan has seen an increase in inbound factory construction from overseas, and she was involved as the main counsel in the construction of a factory for the world's leading semiconductor manufacturer that attracted much attention in Japan.
She is also one of the few lawyers who can support overseas companies from the perspective of the Construction Business Act, which is a major barrier for overseas construction companies. She is familiar with domestic and foreign construction model forms, such as FIDIC, and her experience working for the Ministry of Foreign Affairs makes her an excellent negotiator with ministries and local governments.
