Since its establishment in 1948, Nagahata Seisakusho has been regarded highly for its fine technology in creating ship articles. While products are made for ships, the Porthole and Marine Bell are now popular among house owners and architects as architectural items because of their design and ship-quality sturdy feature. The Marine Bell can be found at the places such as wedding halls, parks, and shopping malls, and the anchor has become a popular gift. The use of our products has been expanding yearly.
