蓮花寺, Buddhist temple in Ibaraki, Osaka, Japan

Rengeji is a Shingon temple of the Koyasan branch in Ibaraki, Osaka Prefecture. Its main hall, rebuilt in 1989, houses a secret principal image of Yakushi Nyorai. In the right side bay stands a wooden Eleven-Faced Kannon from the Heian to Kamakura period, 114 cm tall, with a twisted waist and right foot slightly forward; a Heian-period Jizo statue, 114.6 cm tall, carved from a single zelkova log, stands nearby.

According to the temple's origin account, the monk Gyōki founded it in 729, the first year of Tempyō, after seeing a light shine each night from a pond on the site. Fire destroyed all its buildings during the Ōnin era (1467–1469). Yūshō planned the reconstruction, and his disciple Kaikei completed it in 1720, the fifth year of Kyōhō.

Rengeji's name means "Lotus Temple". Its annual observances are the Star Festival on 11 February, the Flower Festival on 8 April and a Segaki memorial service on 24 August. The temple bell bears the inscription "Zuihozan Shotoin Okunobo, 6th year of An'ei (1777)".

Rengeji stands in the northern part of Ibaraki, Osaka Prefecture, in the area known as Oda. The main hall, rebuilt in 1989, holds the statues of the Eleven-Faced Kannon and Jizo in its right side bay, while the Dainichi image sits in the left bay. The bell tower gate was newly built in 1980 when a temple bell was donated.

The temple's bronze bell, cast with the inscription "1777, Zuihozan Shotoin Okunobo," was melted down for metal during the Pacific War and never returned; a replacement bell was donated in 1980, prompting the building of a new bell tower gate. The bell's inscription had recorded two temple treasures, a Great Perfection of Wisdom sutra in the hand of Ono no Takamura and a Nirvana painting by the monk Son'yu, both now lost.
