1 Litre no Namida

is a 2005 Japanese television drama for Fuji TV. It is based on the story of Aya Kitō, who suffered from a degenerative disease and died at the age of 25. The script is based on Aya's diary that she kept writing in until she could no longer hold a pen. The diary was later titled One Litre of Tears and sold over 1.1 million copies in Japan. Plot Fifteen-year-old Aya Ikeuchi is an ordinary girl, soon to be high school student and the eldest daughter of a family who works at a tofu shop. As time passes, unusual things start happening to Aya. She begins falling down often and walking strangely. Concerned about her health, Aya's mother Shioka takes her to a doctor; he informs Shioka that Aya has spinocerebellar degeneration, a rare disease where the cerebellum gradually deteriorates to the point where the victim cannot walk, speak, write, or eat. As cruel as the disease is, it does not affect the mind.
