I've tasted some great Japanese whiskies, but I don't know the range of stuff there well at all. Nikka has a bar under their office in Tokyo, and I went when I was in town last year to try their range:

I left the country with a bottle of Nikka Yoichi, which is good, but not nearly as good as some of the ones from that tasting, most of which I believe are exclusively bottled for exactly that menu item. So if the question is, "Do I like Japanese whisky?" I can roundly say, "Yes." If the question is if I can recommend any, I'd have to say, "Not really."
Got a bottle of Suntory Yamazaki 12 Year as a gift a while back and really enjoyed it, although it was a bit sweet.
Laguvulin 16, Talisker 10, Glenmorangie 10, Aberlour 10
For bourbon, Buffalo Trace is a great deal (it's not an amazing whisky, but it's great for its price). 1776 Bourbon is quite good, and not very expensive. Bushmills 10 is a nice, relatively cheap, Irish single malt.
Getting out into more exotic stuff doesn't make sense until you've developed your taste for the stuff a bit more since it's expensive. If there's a whisky festival of some sort in your area, at least if they work like the one in Berlin, they're a great place to try a bunch of stuff since 2 cl costs about 1/20th of the bottle price, so you can try a jigger from a €100 bottle usually for €5, or low-end stuff for €2. It's very rare that I'd drop €100 or more on something I hadn't previously tasted, and at said festival, I'll usually try 6-8 exotic whiskies, and then buy a bottle or two.
I can't remember if I've tried the Suntory Yamazaki, but several of the Japanese (and Taiwanese) whiskies I've tried are a bit sweeter; a bit more like a good bourbon.
