Abstract

A flush toilet according to an embodiment includes a bowl part, a rim part, a water spout port, and a water storage part. The bowl part receives waste. The rim part is formed on a top of the bowl part. The water spout port spouts a washing water. The water storage part is formed on a bottom of the bowl part. A first region that is connected to a discharge channel and a second region that is located on a front side of the first region are formed in the water storage part. A main stream of the washing water that is spouted from the water spout port along the rim part swirls on the bowl part and flows into the first region.
