This drama is one of the best dramas I have ever seen! It is based on a true story of a girl called "Aya Kito" who wrote a diary while she struggled with an incurable disease called spinocerebellar ataxia. She battled with the disease for 10 years, before sadly passing away on May 23, 1988. In 1 Litre Of Tears, the story is outstanding. Watching the drama, left a huge impact on me and my heart and I wasted packs of tissues by just watching this- trust me I cried LOADS watching it! The acting was magnificent, Erika Sawajiri ( Aya in the drama) was so amazing. Her crying and scenes were so natural and you could actually see she wasn't forcing her tears. The cast chosen for this drama was perfect as they all fit their characters perfectly well! The music was great as well; the chosen music fitted the scene amazingly and I recommend to you 100% to watch it; this drama is so outstanding. There wasn't a single episode in which I didn't cry! If you are going to be watching it, don't forget your tissues!
