Since its founding in 1951, "Staircase YOKOMORI" has been involved in various staircases both domestically and internationally. YOKOMORI's staircases are used in many famous buildings such as the "Tokyo Skytree," "Roppongi Hills," and "Abeno Harukas." With experience and achievements that have been adopted in about 80% of Japan's skyscrapers, we respond to our customers' requests. We provide precise dimensions that fit perfectly into any building, technical skills that realize the designer's intent, beautifully streamlined production lines, and a commitment to safety and quality. Our mission as "Staircase Makers" is to deliver products that are "reliable" and "safe" for both users and creators. The knowledge and technology we have accumulated over more than 70 years have been adapted into the "Sistair," a visually appealing steel staircase for residential use. We create customized staircases with the ease of standard products and the flexibility of made-to-order designs, working together with our customers.
