Protection of Eupatorium japonicum (Hyogo Prefecture endangered species A rank) and Hemigrammocypris rasborella (Hyogo Prefecture endangered species A rank)
Toshiba Electronic Devices & Storage Corporation Himeji Operations-Semiconductor
Since fiscal year 2013, we have been protecting Eupatorium fortunei (Fujibakama) and Hemigrammocypris rasborella (Kawabata Moroko).Eupatorium fortunei is a perennial herb in the family Asteraceae, distributed in central Honshu, Shikoku, and Kyushu. The individuals protected on our premises also bloom pale pinkish-purple flowers around September.Hemigrammocypris rasborella is a cyprinid fish distributed in western Honshu, northern Shikoku, and northwestern Kyushu. During the breeding season, males develop a beautiful golden coloration. The population of H. rasborella in the pond on our premises is regularly monitored to assess its status and maintain a stable population.

“Implementation of marine organism surveys and coastal shoreline cleanup activities.”
Buzen Toshiba Electronics Corporation
Because the tidal flats of Suō-nada—an area where valuable natural environments remain—are located nearby, we conduct activities that contribute to marine biodiversity together with students from local elementary schools, such as marine organism surveys and learning programs on marine plastic pollution. In addition, we work with local authorities to collect waste that has drifted into Unoshima Port.
Cultivation of Hyogo prefecture flowers - chrysanthemum japonense and aristolochia debilis (dutchman's pipe vine)
Himeji Toshiba E.P. Corporation
The chrysanthemum japonense, which is the official flower of Hyogo Prefecture and is designated as Rank C in IUCN’s Red List as a Near Threatened species of Hyogo prefecture, is conserved and cultivated on the premises. In addition, we are attracting the Atrophaneura alcinous, the official butterfly of Himeji City, to our premises by cultivating aristolochia debilis (Dutchman's Pipe), which is eaten by the larvae of the Atrophaneura alcinous.
Establishment of an ecosystem network through protection activities for rare plants and attracting flying debris
Japan Semiconductor Corporation Iwate-Operations
We planted and cultivated seedlings of rare plant species such as Primula sieboldii (Sakurasou), Primula japonica (Kurinsou), Hemerocallis middendorffii var. esculenta (Nikkōkisuge), and Lysimachia clethroides (Okatranō). In addition, to attract the national butterfly Sasakia charonda (Ōmurasaki), we have also planted seedlings of the Celtis sinensis var. japonica (Ezo-enoki), which serves as a food for its larvae, within the flowerbed. Furthermore, as part of our participation in Kitakami City’s “Flower-Full Movement,” we launched the “Flowering Path Guide Project (Hanazakū Michishirube PJ)” and have planted flowers such as salvia and marigolds.
Conservation of the rare plant Cephalanthera longifolia
NuFlare Technology Inc.
To ensure that the rare plant Cephalanthera longifolia can continue to grow naturally on the premises, we regularly perform maintenance such as weed removal.
Check Dam Construction and Tree Planting Project
Toshiba Semiconductor Thailand Co., Ltd.
At the Khao Eto Waterfall Forest Park in Prachinburi Province, we have been working with the local community since fiscal year 2023 to build check dams and plant trees such as Michelia champaca (Nambansakaichi), Firmiana simplex (Chinese parasol tree), and Queen’s Flower (Lagerstroemia speciosa).In July 2025, we completed the construction of three check dams and planted a total of 280 trees.
