Sarashina Nikki

So we don't know the name of the lady who wrote this diary.

The diary is commonly called the Sarashina Diary, but it's obviously not the actual name.

And then her name is referred to as Sugawara Notakasue Nomusume, but it's literally translated as Daughter of Sugawara Notakasue, so it's not her actual name, obviously.

And we're going to stick with Lady Sarashina, which is a name that was given to her by one of the translators.
