Initiatives to provide low-speed mobility services
This is an introduction to our Impact Assessment key initiatives.
Impact AssessmentAs a last mile mobility solution, we have been deploying compact low-speed electric vehicles based on golf cars in various areas. By providing mobility for elderly persons and other area residents, we are contributing to a fulfilling life for people.

Based on the method of impact weighted accounting (IWA) proposed by Harvard Business School in the United States, we developed the calculation formula and converted social impact into monetary value
* The above operation areas are areas used for daily life purposes where service was in operation for more than two months in the 2023
*The estimated number of users (not the total number of people) is 2,706 people in total. By major area: Chiba Prefecture:873, Osaka Prefecture:572, Shimane Prefecture:302, Kumamoto Prefecture:302, Nara Prefecture:225
Methodology for Calculating Impact Amount
(Medical field) Medical cost reduction:
Estimated number of users*1 × Average number of days when riding × Average increase in number of steps when riding × Medical cost reduction effect per step*2
*1 Calculated by considering fluctuations based on empirical data and interviews with drivers, etc.
*2 Use of the Ministry of Land, Infrastructure, Transport and Tourism's “Guidelines for Walking Volume (Step Count) Survey to Ascertain Health Promotion Effect in Urban Development”
(Nursing care field) Nursing care cost reduction:
Estimated number of users by frequency*1 x Amount of nursing care cost reduction effect*2
*1 Calculated by considering fluctuations based on empirical data and interviews with drivers, etc.
*2 Created by Yamaha Motor citing the results of a joint study with Chiba University
(Environment field)Amount of CO2reduction:
Number of vehicles in operation × Average number of passengers during driving × Total distance traveled × (Gasoline vehicle emissions intensity − Low-speed mobility emissions intensity) × Conversion rate from owner-driven cars × Internal carbon pricing of Yamaha Motor
