The Porte was introduced in July 2004, but is only available in Japan, so it is only produced with right-hand drive.

The Porte is based on the first generation Vitz subcompact car and is made in 4-seater and 5-seater versions.

In July 2012, the Porte was redesigned and for this generation, it introduced the Toyota Spade (Japanese: トヨタ・スペイド, Hepburn: Toyota Supeido) twin model, which sported a different front and rear design, as well as a slightly different interior colour.

Although, it still comes with the 1.3-litre 1NR-FE engine or an improved 1.5-litre 1NZ-FE engine, mated with the Super CVT-i (Continuously Variable Transmission-intelligent) automatic transmission, an available Smart Stop feature for the 1.5-litre variants has a fuel efficiency of 20.6 km/L (58 mpg‑imp; 48 mpg‑US) under the JC08 test cycle (equivalent to 113 g/km (6.4 oz/mi) of CO2 emissions) of the Japanese Ministry of Land, Infrastructure, Transport and Tourism (MLIT).
