Social Contribution Activities

Our Social Contribution Activities
As a company, we value contributing to society through our business activities and by building a good relationship with our community. We engage in a variety of social contribution activities to support the development of culture and sports, including operating Hayashibara Museum of Art and holding the Hayashibara Life Seminar, as well as organizing events and gatherings to promote interaction and positive communication with the local community.
Support for Hayashibara Museum of Art
The museum houses a collection of Japanese and other East Asian paintings, crafts, and other items. The museum also exhibits furnishings inherited from the estate of the feudal Ikeda clan of the Okayama Domain. The collection includes three national treasures and 26 important cultural goods including: swords, arms, armor, paintings, writings, Noh masks and costumes, carved lacquer, mother-of-pearl work, lacquerware, ceramics and metal works.
The goal of the museum is to contribute to research of cultural goods and improve the culture of the region and of Japan. It does this by preserving works of art, conducting research on them, and allowing the general public to enjoy them through unique exhibitions and other events.
By supporting the Hayashibara Museum of Art, we can contribute to the recognition of the rich culture and history in our community, and help in passing down these cultural goods for future generations.

The Hayashibara Award
First awarded in 1963, The ‘Hayashibara Award’ is ‘an annual award recognizing and rewarding one to four young scientists’ from Okayama University School of Medicine for their hard work in the ‘promotion of cancer research and eradication of cancer’.
Since 2013, the prize has been renamed the “Hayashibara and Yamada Prizes for Cancer Research” at Okayama University, and in 2020, the prize will be awarded to three recipients. 109 recipients have been awarded to date, and the recipients are currently working at the forefront of cancer treatment.
Sponsorship for Sports and Culture in the Community
To give back to sports and culture in the community, we sponsor a variety of organizations in Okayama. As for major sponsorships, we have been the uniform sponsor of the Okayama Seagulls, a women's volleyball team, since 2015, the club sponsor of Fasiano Okayama, a J2 soccer team, since 2016, and the official partner of Trihoop Okayama, a B3 basketball team, since 2020. In addition, we support the Okayama Philharmonic Orchestra, an orchestra based at Okayama Symphony Hall, as a supporting member.

Protection of Cultural Goods Using Our Products and Technologies
To help preserve our community’s rich cultural history, we have used our enzyme technologies to develop important materials to be used in the protection of cultural goods
Conservation Treatment of Buried Cultural Properties with Trehalose
The organic materials found in the excavations, such as wooden boats, farming tools, and lacquerware, have lost their strength due to the destruction of their cells by microorganisms. They also contain excessive moisture, which causes them to shrink violently when dried as it is. In order to preserve them in good condition, they need to be impregnated with substances that strengthen their cells and stabilize them in a dry state.
Conventionally, the polyethylene glycol (PEG) impregnation method have been used to preserve excavated wood products. However, there were problems such as the impregnation process taking a long time, and in the case of wood-iron composites and items excavated from underwater sites, the material deteriorated after impregnation treatment. To solve these problems, "The trehalose impregnation treatment method" was developed by a research group led by the Conservation Science Office of the Osaka City Cultural Properties Association and is now widely used both in Japan and overseas. in March 2021, the impregnation treatment of a 5.5m bulkhead plate of the Mongolian invasion sunken ship excavated from an underwater site in Takashima, Matsuura City, Nagasaki prefecture was completed.

Developing Alternative Aged Paste, Essential for Repairing Hanging Scrolls and Scrolls, through Enzyme Technology
Aged paste is an adhesive essential for the repair of cultural goods using Japanese paper, such as hanging scrolls and scrolls. Its properties ensure the paper does not harden after drying, prevents molding, and easily peels off when water is applied. In the repair studio, art conservation experts produce aged paste by maturing boiled wheat starch for 10 years. It takes an enormous amount of time and effort, and ensuring a stable supply is difficult. In partnership Tokyo National Research Institute for Cultural Goods and Oka Bokkodo Co., Ltd, (a cultural goods repair company), Hayashibara started the joint development of alternative to the traditionally made aged paste. Together, they succeeded in manufacturing an alternative aged paste through enzyme technology, that can be produced in a period of two weeks.

Mass-Production of an Enzyme to Remove the PVA Membrane Applied as an Anti-Delamination Agent on the Surface of Cultural Goods, such as Mural Paintings
Polyvinyl alcohol (PVA), used to protect mural paintings in architecture, deteriorates over time and can cause damage to the surface it’s applied on. Art restoration experts have long been concerned with how to safely remove it without damaging the art. The Osaka Research Institute of Industrial Science and Technology has developed an enzyme that degrades PVA. Hayashibara produces this PVA degrading enzyme, and provides it to Tokyo National Research Institute for Cultural Goods for use in art restoration to ensure the PVA can be removed safely, without damaging the art.
