Mimo Shrine (御裳神社/Mimo Jinja) in Ichinomiya-shi (一宮市), Aichi, blew up on social media recently because of a Temizuya (手水舎 - a Shinto water ablution pavilion for ceremonial purification) that's full of colorful hydrangeas (あじさい/Ajisai).

Mimo Shrine has about 70 species of hydrangeas, totaling around 8,000 flowers, and is home to the Bisai Hydrangeas (尾西あじさい祭り/Bisai Ajisai Matsuri) Festival every year. The festival includes events such as night illumination, a hydrangea seedling market, and tea rooms.
