Be sure to go at night. The fluorescent floor is like stars all over the sky. A week's walk around the top terrace gives us a bird's eye view of Osaka City's bright night scenery, which gives us a feeling of ecstasy, of the prosperity and vastness of the city, of the vast traffic flow mixed with neon stars flashing. The beautiful Dianchuan River spans Osaka Harbor and Central District. The 13 Bridges and the 13 New Bridges spanned the Dianchuan River with flashing lights. If you have a lover, you must find a heart lock at the top of the heart lock wall to lock in love and love for life.
