Higashiyama Zoo and Botanical Gardens in Chikusa Ward, Nagoya, is running its Night Zoo & Garden event from Aug. 6 to 8 and 13 to 15.

This is the fourth year the night event will be held, but the first time the botanical gardens will be opened at night. The zoo will also expand accessible areas, including the monkey zone.

The event started in 2007 with the aim of giving visitors a chance to take in the park's atmosphere at night and watch the animals' nocturnal behavior, which they usually don't have an opportunity to see. The number of visitors has been rising annually, and reached nearly 150,000 last year.
