Experiencing new things during your travel is great! If you are looking to do something new in Japan, how about climbing Mt. Fuji (from spring to summer), or skiing in Nagano or Hokkaido in the winter? Or, if you want to try something new food-wise, why not to try Okonomiyaki, Teppanyaki, or Teriyaki dishes? You can find tours on HIS and/or JAPONICAN, both are popular travel websites that offer a number of tour packages. Many people post reviews of their tours, which are potentially powerful resources for constructing travel plans.
