Ishizaka Sangyo Co., Ltd. is celebrating its 55th anniversary and will be renewing its corporate mark.
To mark its 55th anniversary this year, Ishizaka Sangyo Co., Ltd.* has redesigned its corporate mark to further clarify its corporate identity , under
the creative direction of graphic designer Taku Sato . *Head office: Iruma-gun, Saitama Prefecture, Representative Director: Noriko Ishizaka, hereinafter referred to as “Ishizaka Sangyo” <New corporate mark>

① New corporate mark
Ishizaka Sangyo has adopted the vision of “Zero Waste Design*” to realize a sustainable society, and operates an industrial waste intermediate treatment plant that puts the SDGs into practice, as well as the environmental education field “Mitomi Konjaku Mura.” The new corporate mark is based on green, which represents a sustainable earth, and uses the kanji character for “stone,” which is part of the company name, as a motif, pointing out the direction from the environment to the future. The angle in the upper left corner is 100 degrees, visually conveying the strong determination to aim for 100% waste reduction and recycling rate.

The shape of a “stone” symbolizes recycling . Graphic designer Taku Satoh.
Ishizaka Sangyo is a company that handles industrial waste. While we now live in an age where society as a whole is paying attention to the environment through the SDGs, Ishizaka Sangyo has been one of the first to undertake various initiatives centered around “circulation,” including waste recycling, satoyama revitalization, and renewable energy utilization. Having reexamined our previous visual identity, we have created and proposed a new mark with the words “Designing Circulation.”
While circulation is often expressed as a circular ring, I have long felt uncomfortable with the idea of a ring returning to the same place. Therefore, I created a mark that expresses a circulation that does not return to the same place, in other words, a spiral, by superimposing the kanji character for “stone” (石), which is Ishizaka Sangyo’s name, on top right. The “scale” in the Mincho font on the top right is made into an arrow, expressing Ishizaka Sangyo’s strong will to rotate (circulate) and turn the corner to reach the next destination.
