In December 2008, Taiji's staff announced on his blog that since September, his epilepsy and chronic strokes had worsened, that he was suffering from necrosis after a hip joint replacement of the femoral component on his left hip, and that on December 2, he was hospitalized again after falling and hurting his chest and throat. 2010–2011: TSP, Reunited with X In 2010, he formed TSP (Taiji & Shu Project), with Taiji on bass, guitarist Shu (Cloud Nine, Crazy Quarter Mile), vocalist Dai (Taiji with Heaven's) and drummer Hina (Crazy Quarter Mile).
