Toha Heavy Industries (東亜重工, Tō-A Jūkō; Tō-A can be interpreted as "East Asian") exists in fiction as a megacorporation appearing in many of Nihei Tsutomu's works, including Blame!, Biomega, and Sidonia no Kishi. In real life, Toha Heavy Industries is the company that Nihei founded to manage his own brands as seen on his official website, http://toahi.net/. Its logo looks like a stylized "t".
