ロンタイ Company Profile

For 60 years with the greenery of this country, we will connect the green landscapes to the future.

Gentle green spreads across the slopes of the road, blending into the landscape. This green may be what is called "slope greening," which is planned and planted during road construction. Our work in slope greening aims to prevent slope collapse, protect people's lives and communities, and restore damaged ecosystems. With the belief of "green that protects people," Rontai is committed to greening efforts.

Business Activities

Manufacturing and sales of civil engineering greening materials and greening construction.
