I was in Beppu, Japan (photos) for hiking. It’s a hot springs resort much well liked.

… The volume of water discharged is second only to that of the Yellowstone National Park in the United States, the largest hot spring resort in the world. …

Heather Fidyk recommended Takasakiyama Monkey Park, a short bus ride from town.

Japanese macaques can be dangerous, yet you can walk as close as you like.

Feeding time is CRAZY.

Note:

An introduced free-ranging population has been living near Laredo, Texas since 1972.

More northerly than those I saw in the wild in Florida.
