Movie director Kumai Kei died yesterday at a Tokyo hospital after suffering a brain hemorrhage. He was 76. As reported here on Monday, Kumai was taken to the hospital last Friday after a newspaper delivery man discovered him unconscious outside his Tokyo home. He was best known for tackling social issues in movies such as the hugely successful “Kurobe no Taiyo” (Tunnel to the Sun, 1968), about the construction of the famous Kurobe Dam, and “Umi to Dokuyaku” (The Sea and Poison, 1986), which won the Silver Bear award at the Berlin International Film Festival.
