Overview

Yotai is a mid-tier industry company based in Kaizuka City, Osaka Prefecture, founded in 1936, specializing in the manufacture of refractory materials and fine ceramics. It has established a solid position through the production of refractory bricks for the steel and cement sectors as part of the Sumitomo Osaka Cement group.

Current Situation

Yotai recorded consolidated sales of approximately 29.1 billion yen and operating profit of about 3.6 billion yen in the fiscal year ended March 2024, maintaining a solid financial foundation. It focuses on the manufacture and sale of refractory bricks, unshaped refractories, and new ceramics, holding its position as a core supplier to the steel and cement industries. With multiple factories and research institutes, it also handles advanced kiln and furnace design and construction services, enabling integrated upstream and downstream services. In recent years, it has expanded overseas operations through the establishment of a Chinese subsidiary and capital alliances. It is strengthening its R&D structure, pursuing technological innovation and quality improvement, while also developing environmentally friendly refractory materials. The 2025 tender offer by ASNF Holdings aims to strengthen the group, targeting enhanced mid- to long-term competitiveness in the market. Moving forward, backed by stable growth in the refractory materials market, it plans to focus on new material development and kiln construction technologies to further solidify its industry leadership.
