Zoos open at night. A Ferris wheel still running past midnight.

Such scenes are becoming more common at leisure facilities as revenues continue to decline.

Take Ueno Zoological Gardens in Tokyo's Taito Ward for example. Aiming to stem a decline in visitors, the nation's oldest zoo from Aug. 15 to Aug. 17 remained open until 8 p.m., three hours longer than usual, and offered special events at night.
