Each year, the Head Office of Mazda (Hiroshima) participates in one of the largest festivals in Hiroshima Prefecture, the "Hiroshima Flower Festival," which has been held annually during a long holiday week in May, since its inception in 1977. The Mazda Plaza holds events enjoyed by both children and parents alike, and also displays Mazda vehicles.
In FY2019, as a support activity for the reconstruction areas affected by the heavy rains in 2018, Mazda sold refreshments using ingredients from disaster-affected areas and made banners together with visitors with messages of support at the Mazda Zoom-Zoom Plaza. Mazda also provided a stage in the plaza for dance performances in order to support children in disaster-affected areas. The venue was filled with warm applause and cheers in response to the children's smiling faces and energetic performances. Additionally, many events were held, including donations of welfare instruments, a charity bingo tournament to raise funds for Mazda's social contribution activities, songs and dances by local residents, performances by buskers, and a talk show given by Hiroshima Toyo Carp and Sanfrecce Hiroshima players.

The Hofu Plant has been participating every year in the "Love Hofu Flea Market," which is held by companies, the Chamber of Commerce and Industry, the local government, and shopping centers as the leading event of the "Love Hofu Campaign," since the first time it was held in 1993. As the secretariat of the Love Hofu Campaign Promotion Companies, the Hofu Plant participates in planning and running the flea market, and presents the Mazda booth jointly with partner companies.
In FY2019, around 250 employees and management members from the Hofu Plant worked as volunteer staff. They sold goods and refreshments, as well as set up a space for games and Mazda car displays that guests of all ages could enjoy, and helped the organizers run a stamp rally. Some of the money from sales was donated to welfare organizations in Hofu City or used as funds for operating the flea market.

Jointly with Mazda Group companies in Miyoshi City, the Miyoshi Office participates in events, helping revitalize communities while deepening exchange with local residents. Moreover, as a corporate member of the Miyoshi City Tourist Association and the Miyoshi Chamber of Commerce and Industry, the Miyoshi Office provides support for organizing events.
The Miyoshi Office has participated in the Miyoshi Commerce and Industry Festival every year since its inception in 1993. The office had a booth at the Festival in FY2019 as well.
Since 2016, a bus tour of the Mazda Miyoshi test course has been offered as one of the attractions. FY2019, the attraction's fourth year, saw 644 participants – the most yet. During the tour of the high-speed circuit, the bus was stopped to allow visitors to climb the 45-degree angle bank on foot. Participants commented, "I want to come back next year" and "The tour, where I could see each test course and facility out of the window, was interesting and easy to understand thanks to the explanations from employees who work there."

Yoshiwa Kogyo, which manufactures and sells automotive parts, concluded in June 2007 an agreement called "Community and Business Partnership (One Village, One Company: Shimane)" with Yoshika-cho in Shimane Prefecture, where its plant is located. Through this partnership, the company supports community revitalization and actively participates in community activities. Yoshiwa Kogyo continued supporting the Yoshika-Yume-Hana Marathon event annually hosted by the Yoshika School Board in FY2019 as well.
