Special Feature: Automated Driving and MaaS


Today, the automotive industry is said to be entering a once-in-a-century period of transformation. At the core of this transformation is a series of technical innovations called "CASE" (Connected, Autonomous, Shared/Service, Electric), which is represented by new technologies and services such as "automated driving" and "MaaS" (Mobility as a Service).

For many years, we have provided legal services for our clients including domestic and overseas automobile manufacturers and automotive parts companies. In order to deal promptly with the arrival of this transformational period, we have established a support system for the automated driving and MaaS fields ahead of any other law firm.


"Regulations on Autonomous Cars and MaaS Businesses" was published on June 23, 2020.
This is an unprecedented book that broadly explains the legal systems in relation to automobile-related businesses, such as automated driving and MaaS, as well as connected cars.
