Eifuku-ji Temple is said to have been built by Empress Suiko to protect Prince Shotoku, his mother Empress Anahobe no Hashihito, and his wife Kashiwabe no Oiratsume, and the large temple complex was built by Emperor Shomu in 724. Eifuku-ji Temple is also known as "Kami no Taishi" (Upper Prince), and during the Heian period when worship of the prince was popular, he was one of the "Three Princes of Kawachi" who received pilgrimages from many people, along with "Naka ​​no Taishi" (Middle Prince) of Nonaka-ji Temple in Habikino City, and "Shimo no Taishi" (Lower Prince) of Daisho Shogun-ji Temple in Yao City. At the end of the Sengoku period, the temple was burned down by Oda Nobunaga, but in 1603, Toyotomi Hideyori rebuilt the "Holy Spirit Hall." Since then, the "Tahoto Pagoda" and other structures have been rebuilt one after another, and remain in their current state (both are designated as important cultural properties of Japan). Every year on April 11th and 12th, the "Daijo-eshiki" ceremony is held to commemorate the anniversary of Prince Shotoku's death, and under the cherry blossoms in full bloom on the temple grounds, a memorial service is held, along with tea offerings by the head of the Omotesenke school, a fire Homa ceremony, and rice cake throwing.
