Hankyu Sun Square is a plaza and underground mall in Umeda, located below Hankyu Umeda Main Store and connected to the crosswalk in front of HEP FIVE. It is used as a photo spot where the Umeda letter-shaped bench and the red HEP FIVE Ferris wheel fit in one frame. The underground passage connects to Whity Umeda and reaches JR Osaka Station without using many stairs, and events or monuments sometimes appear below the escalator on the HEP FIVE side. The passage is not roofed along its entire length.
