This is a Tokyo Koiki Kojiguchi shirt. The size tag has been removed, but I believe it's a size 4. It's likely suitable for a child aged 7-8, around 125cm tall. Length is approximately 53cm, and width is approximately 38cm. It has a white base with a floral pattern and a design resembling Komainu (guardian lion-dogs). I wore it for about 7 days in total. There is no noticeable damage. Available for immediate purchase.
