K2,
nydad, thanks for bumping up one of my favorite threads in Japan forum.
Here we have
jpatokal's awesome trip report and 2010 JAPAN FORUM
PLAYMATE PRIMATE OF THE YEAR introduced by
megatoplover and
jib31 earlier this year. (aka wild monkeys bathing in hot springs in Nagano)
jpatokal also wrote WikiTravel articles about
Shirabu Onsen and
Onogawa Onsen, both of which are worth reading.
