When I lived in Hokkaido, I liked visiting the Maruyama Zoo in Sapporo. I recently read that four Asian elephants that were given to Sapporo by Myanmar last year made their public debut on March 12th. This has been a very controversial acquisition because of the extreme cold in Hokkaido and elephants coming from a much warmer area.
This is the Hokkaido's first time having a herd of elephants. The total area of the elephant house is about 5,200 square meters making it one of the largest in Japan. The zoo opens at 9:30 am, but the elephant house takes a long time to clean every morning so they can be seen from around 11 o'clock each day. You can check out the zoo website here.
