In Osaka, two iconic structures, Osaka Castle and Shitenno-ji, showcase the work of construction firm Kongō Gumi, the oldest continuously run company in the world. Founded in 578 to build Shitenno-ji, Kongō Gumi operated independently for over 1,400 years before shifting to coffin crafting due to changes in demand during World War II and the collapse of Japan’s real estate market. Despite now being a subsidiary, Kongō Gumi continues its legacy with highly skilled artisans, using traditional tools and techniques that have been refined over centuries. The company’s ability to adapt to challenges highlights its long history of innovation and craftsmanship.
