Uchimata Makikomi is a throw involving an inner thigh lift with the leg, while wrapping the arm and falling.

Judo is made up of throwing (nage), grappling (katame or ‘newaza’) and striking (atemi) techniques.

The throwing techniques are split into standing techniques (tachi-waza) and sacrifice [falling] techniques (sutemi-waza). In turn, the standing techniques are split into hand techniques (te-waza), hip techniques (koshi-waza) and foot techniques (ashi-waza).

Uchi Mata using a Whizzer or Overhook grip with your arm is effective. This video shows how to use the whizzer grip along with a near lapel grip and how to use the whizzer grip without a near lapel grip in doing Uchi Mata.
