空中庭園 (Kuuchuu Teien)

Song Meaning

The lyrics paint a vivid picture of stumbling upon a hidden, almost dreamlike place, a "空中庭園" (Kuuchuu Teien – aerial garden). The narrator opens a vine-covered door and is drawn into a world so bright and filled with the sound of water that it feels otherworldly. This initial immersion suggests a sudden, unexpected transition into a realm of pure memory or imagination, a place distinct from the ordinary sky or ground.
