Now look at the main halls. They follow a style that takes its name from this shrine: Hirano-zukuri, also called hiyoku Kasuga-zukuri, or twin-winged Kasuga style. There are four small Kasuga-style sanctuaries, one for each deity, joined two by two. A crosswise ridge links each pair and forms a connecting space between them, with a shared porch at the front. The result looks, at first glance, like a single wider hall. They face east, were built in the Kanei era, with the south hall dating to 1625 and the north hall to 1632, and are designated Important Cultural Properties. The worship hall was donated by Tofukumonin and is known as the grafted worship hall. Its plaques of the Thirty-Six Poetry Immortals are by Kaihoku Yusetsu. Then there are the cherries. Tradition credits Emperor Kazan with planting them, and from the Heian period the shrine has been a renowned blossom spot. In the Edo period ordinary townspeople came for the Hirano night cherry blossoms. There are about 400 trees of dozens of varieties, with names such as Sakigake, Nezame, Hirano Imose and Taoyame. The flowering stretches from mid March to late April, and in early April the red weeping and Yoshino cherries are at their finest.
