Suggestions for onsens near Nagasaki

Hi,

At the moment i am in Kyoto, Japan and have been using this site and forum a lot, so thanks.

I have booked hotels in Japan till the 18th of november, when i have to check out in Nagasaki. I will probably take the ferry from Hakata to Busan in South-Korea on the 21st of November.

If anybody has some suggestions to do between the 18th-21st of November that would be much appreciated. I do not have a Raill Pass at that moment, so preferably not to far away.

Any suggestions where i should or could go? Also, i have not been in an onsen or hot springs since i arrived in Japan, if anybody knows a hotel with onsen or close to hot springs near Nagasaki that would be fun to do to for a few days.

Thanks for any info.

Unzen Onsen! It has some great waters in a nice natural environment on the slopes of the recently active Mount Unzen. There is also a large, attractive "hell", i.e. the area where hot water, mud and volcanic gases surface:

Obama onsen, Ureshino onsen, Takeo onsen, Unzen onsen and many more. Karatsu, Yobiko, all along the Japan Sea side offer great fresh sea foods.
