Overview

JK Holdings is the largest company in the building materials and housing equipment wholesale industry, founded in 1949. It is a specialized trading firm for construction materials with numerous bases nationwide and its own private brands.

Current Situation

JK Holdings recorded consolidated sales of approximately 407 billion yen and ordinary income of approximately 10.3 billion yen for the fiscal year ended March 2023, solidifying its position as the domestic leader in the housing equipment wholesale industry. Its core building materials wholesale business accounts for about 82.5% of sales, covering the supply chain from manufacturing to sales through numerous subsidiaries. In recent years, it has absorbed the impact of the wood shock through its own manufactured products, improving profit margins. By developing private brands such as domestic wood 'J-GREEN,' it has achieved stable supply and value-added offerings. Through its wood structure construction group, it has expanded into non-residential fields, focusing on housing application support for carpenters and developing new sales channels. Aiming for a decarbonized society by 2050, it emphasizes promoting domestic wood use and sustainable forest resource utilization. Toward 2030, it is strengthening ESG initiatives and stabilizing the domestic market, specializing overseas activities in procurement and leveraging domestic business strengths. Strengthening wooden construction technology and utilizing logistics networks are key pillars of growth.
