Corporate Strengths

We have been recycling waste plastic to manufacture and sell markers and construction materials since we were established nearly 50 years ago. In addition, in order to increase the added value of our stake markers, we have also developed “Information Stakes” with built-in IC chips and stakes with built-in sensors to detect landslides.

Unique, Best-Selling Products and Services

■ Recycled plastic stake (Domestic share: 60%)

We manufacture stakes for marking borders as well as fenceposts, based on technology for recycling waste plastic that we have cultivated since we were established. Our stake markers have the top share in the Japanese market, and are sold throughout Japan. We have built an in-house system that allows an integrated process of production, from orders received to material procurement, manufacturing using our own original design equipment, and delivery. There are 3 keys to the concept of consistency in our recycling business: (1) ” Monozukuri” as part of the manufacturing industry, (2) “Environment” such as measures to protect the global environment, and (3) “Information” through collaboration between positioning information and IoT.

Appeal to New Graduates/Mid-Career Recruits

We pursue all possibilities regarding recycling, and develop products such as stake markers with high added value while improving our recycling technology, and work actively to develop new recycling materials.
