A new autobiography of Ryuichi Sakamoto, who died in March at the age of 71, will include entries from a diary that he kept sporadically over the last two years or so of his life.
"Boku wa Ato Nankai Mangetsu o Mirudaro" ("How many more times will I watch the full moon rise?") will be released by Shinchosha on Wednesday.
Sakamoto wrote about his thoughts on life and death, as well as music, in approximately 30 entries in the diary, which were either handwritten or saved on his personal computer or smartphone.
