Tobikomizuki: start in Shizentai (natural stance - i.e. one leg slightly in front of the other shoulder width apart). Jump forward with the lead leg, as you land perform a snap punch to the head with the lead hand (i.e same hand as the lead leg). Might I add, that in Wado, that this is a raising punch, the punch raises up, as you lunge forward, therefore the aim is to hit the opponent, right under the chin. TobiGyakazuki...Lunging Reverse punch...or as Fish mentioned Gyakuzuki No Tusikomi, or leaning reverse punch. In the Wado style, I do, this punch looks awkward..you basically end up in a Nahanchi stance (hourglass stance) doing a leaning reverse punch to the lower area of the opponent. The lead foot is just slightly ahead of the back foot, in fact, the big toe of the back foot should be in line with the heel of the front foot. It is not a comfortable stance to be in for any length of time. Tobi can also mean Flying/Jumping...so Maetobigeri, would be a jumping front kick.
