Taiei is located on Route 51 from Narita to Sawara. It has a very scenic countryside with views of the Narita International Airport runways and aircraft. At Raikodai there is a large industrial estate.

Modern Taiei Town was established on February 11, 1955 through the merger of the villages of Shoei and Osuka.

On March 27, 2006, Taiei, along with the town of Shimofusa (also from Katori District), was merged into the expanded city of Narita, and thus no longer exists as an independent municipality.

In February 2006 (the last data available before its merger into Narita), the town had an estimated population of 12,507 and a population density of 247 persons per km². Its total area was 50.57 km².
