The Daihatsu Boon (Japanese: ダイハツ・ブーン, Hepburn: Daihatsu Būn) is a subcompact car produced by Japanese automaker Daihatsu since 2004, and also sold under Toyota brand as the Toyota Passo (Japanese: トヨタ・パッソ, Hepburn: Toyota Passo) between 2004 and 2023. The Passo was once sold at Toyota Corolla Store Japanese dealerships until it was consolidated with other Toyota dealers in 2020.

Outside Japan, the first- and second-generation Boon is sold as the second- and third-generation Sirion. The first-generation Sirion was sold as the Storia in Japan.

According to Daihatsu, the name "Boon" is derived from the English word boon, and also inspired by the sound that Japanese children make when imitating the sound of a car,^[1] while the name "Passo" is Italian for "step". According to Toyota, the name conjures up the image of a casual and approachable car.^[2]

The development for the first-generation Boon was led by Toyota chief engineer Tetsuya Tada.^[4] For the Japanese domestic market, the Boon were available with 996 cc and 1.3-litre engines. The major difference between the Japanese Boon and Sirion are automatic version where the gear-changing located beside the steering on the dashboard and the handbrake below the steering. Both the Japanese Boon and European Sirion were offered in both front-wheel drive and four-wheel drive versions. A 936 cc turbocharged version with four-wheel drive was also available, known as the Boon X4.

The Boon was designed for European tastes and the model took on a larger and stockier frame. It weighs about 940 kg (2,072 lb). With the back seats down, its luggage capacity increases from 225 L (8 cu ft) to 630 L (22 cu ft).

In early 2005, Daihatsu launched the Japanese-built 2nd generation Sirion in Brunei using the facility and parts from the Boon. The model was discontinued in 2010 before Daihatsu exited the Brunei market as the passenger cars market (except the commercial vehicles) in 2014 and the Sirion is replaced by the Perodua-badged Myvi, which is launched in the country since April 2016.

On 25 May 2005, Malaysian automaker Perodua launched a variant of the Boon known as the Perodua Myvi. Sporting a few cosmetic differences, the Myvi became Perodua's best-selling car in Malaysia for 2006, 2007, 2008 and 2009.

On 25 December 2006, the Boon was restyled. This version was exported to Europe as the Sirion in 2007.

In 2007, Daihatsu launched the Sirion in Indonesia using the facility and parts from the Myvi.^[5]

The Subaru Justy was unveiled at the 2007 Frankfurt Motor Show using the Boon model. It is positioned as an entry-level model in Subaru's lineup.^{[citation needed]}

In April 2013, Toyota New Zealand announced its decision to stop selling the second-generation Sirion, still on sale, stating it was unable to secure Daihatsu products that comply with future regulatory standards for New Zealand.

The second-generation Sirion was discontinued in South Africa in April 2015, when Daihatsu left the South African market.^{[citation needed]}
