Shichimi Togarashi is a classic Japanese pepper blend.  It uses a different pepper, the sansho peppercorn, which is a cousin of the Szechuan peppercorn found in chinese five spice.  Both give a slight numbing effect to the mouth which is definitely distinct from the capsaicin of black pepper.  It has distinct flavors of orange, toasted sesame, ginger with hints of nori.  You will not be disappointed in this spice blend.  The original seasoning mix pack a serious heat punch coming it at 8-9/10 so I formulated a mix using less of the hotter components allowing for those that like to live in the mild range to enjoy it.
