日東化成工業 Company Profile

"Putty" - A top domestic manufacturer! Nitto Kasei Industry, the putty company, supports society in unseen ways!

Lifelines such as electricity, water, and gas are essential foundations that support daily life and urban activities. Our company manufactures and sells sealants (putty / industrial clay) and adhesives required for the maintenance of these lifelines. Since the launch of our putty (Neoseal, Plaseal) in 1956, it has been used in various fields including construction, shipping, and railway vehicles, with a particularly strong track record in public works. We have maintained the top market share in Japan since its release, and with a unified system of sales, technical development, and manufacturing, our employees continuously propose unique products from the customer's perspective. Additionally, our Okayama factory has obtained not only 'ISO9001' and 'ISO14001', but also the rare certifications for a small to medium-sized enterprise: 'MED (Marine Equipment Directive)' and 'Ministry of Land, Infrastructure, Transport and Tourism Manufacturing Facility Certification'.
