Nikka whisky is offering two-day whisky making workshops at its Yoichi and Miyagikyo distilleries. The "My whisky tsukuri" (My whisky making) workshops will be held September-November at Yoichi and in September-October at Miyagikyo.
In the Yoichi version, the whisky made during the event will be aged for 10 years, and then the people who attended can get bottles. At Miyagikyo, my understanding is that there will not be any actual whisky distilling but there will be blending, coopering etc.. They have been running these events for some time now and they seem to be great fun.
There are still places for the autumn sessions (Yoichi schedule, Miyagikyo schedule) but they only let 20 people onto each course, and draw lots if they receive too many applications. (The popularity of these things seems to be increasing very sharply, so that is quite likely. You need your applications in soon). Cost is 18,000 yen per person and the events are limited to people aged over 20. Hotel accommodation is not included.
More details of the Yoichi events are available here and of the Miyagkyo events here. All of the information there is in Japanese, but I get the feeling people going on this might need some ability anyway to get the most out of it.
