Mysterious Island is every bit what it suggests, and then more. This spectacular land is the most iconic at Tokyo Disney Sea, and at night, its moody atmosphere is touched off by its rugged and spectacular landscape lit in evocative and magnificent manner. Those deep blues and purples are so stunning and romantic, and the curving pathways, earth exploration vessels, and overall steampunk aesthetic make for something that is otherworldly and surreal.
And to think... photos don't really do the place justice.
Mount Prometheus looms even larger from near water level within Mysterious Island.
