Sponsorship of MASTGOLF
MIRARTH HOLDINGS has been sponsoring "MAST GOLF," an initiative launched by a group of volunteer female professional golfers, since fiscal year FY2024.
Under the slogan of "M-Manabu (Learn), A-Asobu (Play), S-Sodateru (Grow), and T-Tanoshimu (Enjoy)," MAST GOLF utilizes Starting New At Golf (SNAG) golf* and regular golf to create environments where children can take on new challenges. They also focus on fostering intergenerational community exchange and making a positive impact through charitable activities.
We supported the ”Bread Donation to Kodomo Shokudo (Children’s cafeteria)” initiative as part of this activity. In FY2025, we donated vegetables harvested at our Leben Village. On the day of the event, dishes made with the vegetables were served to the participating children and their parents.
- * A new form of golf born from years of research by former PGA Tour players in the United States. The keywords are "for children and adults," "fun," and "learn the fundamentals of golf." With simple rules and humorous items, it is ideal as a "Starting New At Golf" and a sport that can be enjoyed even in limited spaces.
Participation in the "No Single-use of Umbrellas by 2030" Project
MIRARTH HOLDINGS Group is participating in the "No Single-use of Umbrellas by 2030" and is cooperating with the umbrella sharing service "i-kasa" as part of this project.
With "Making rainy days comfortable and happy" and "No Single-use of Umbrellas" as the missions, i-kasa is Japan's first full-scale umbrella sharing service launched in December 2018. Instead of buying a plastic umbrella every time you come across sudden rain, by using the dedicated application, you can borrow i-kasa, a durable umbrella, at a train station or in town, and return it to the nearest return location when it stops raining. With over 800,000 registered app users, the service is available across 12 prefectures, including the entire Tokyo metropolitan area, Kanto, Kansai, Aichi, Okayama, Fukuoka, and Saga, with more than 2,000 spots installed.
Our Group has been supporting this project since 2023, actively promoting the use of “i-kasa ” with the goal of achieving zero single-use umbrellas and zero umbrella waste.
"Yajirushi" Emergency Shelter Signs Win Kids Design Award
As a developer engaged in community building through the sale of newly built detached homes, Leben Home Build creates and installs “Yajirushi” (meaning arrow) evacuation guide signs. This initiative stems from our belief that “residential areas with few landmarks require clear, easy-to-understand directional signs to shelters for everyone, especially young children.” To support disaster preparedness education for children across the community, the signs are installed in visible locations, such as garbage collection points along main roads within the Company's residential developments. Designed with minimal information and simplified expression to be easily understood by children, yet incorporating a high level of creativity, "Yajirushi" received the Encouragement Award in the FY2019 Kids Design Award. As of the end of March 2026, the signs have been installed in 27 properties.

Through cleanup activities, we will fulfill our corporate social responsibility by keeping the areas we are involved in hygienic and contributing to the healthy development of local communities. In addition to cleaning up to protect the sanitary environment around condominiums supplied by Group companies, sites under construction, and solar power plants, we are also actively involved in cleaning up the areas around our offices, which are the bases for our employees' activities. We also participate in regular beautification activities organized by local municipalities and neighborhood associations, aiming to strengthen partnerships and cooperative relationships in the community.
