Haus Ten Bosch is a Dutch Themepark located a short train ride away from Nagasaki. It costs a fair deal to get in, but it is worth it. If youve been to Holland, expect a over-the-top-extremeist view of things. Its a laugh!! Dont forget to get some "Amsterdam" postcards to send home before you leave - just to confuse everyone :)
Unzen Jigoku is also near Nagasaki, though less easy to get to with buses going there rarely. We only just missed the 9am bus, having to wait til 10.15 for the next one. Check the timetables and arrive at the bus stop with 15 minutes to spare (Our 9am bus left at 8.50). Once there, get ready for a PONG! It smells like.. rotten eggs or an eggy fart. Yummy. !!?? The water here is supposed to have medicinal factors, so, you could brave it and head straigh for the Onsens there. Or, alternatively, I saw many old ladies washing themselves in any kind of bubbling white water they found. Its a great experience.
