Since there is no description about the temple's founding in the "Nihonshoki" (Chronicles of Japan) nor in the "Horyu-ji Garan Engi narabini Ruki Shizai Cho" (The origin of Horyu-ji Temple and record of construction materials), many details remain unclear.
当寺の創建については、『日本書紀』や『法隆寺伽藍縁起并流記資材帳』（ほうりゅうじがらんえんぎならびにるきしざいちょう）には記載がなく、不明な点が多い。
