A second generation FA/DA was introduced in 1964 and was built in Japan until 1980, when Hino replaced Toyota's heavier truck lines entirely.

Introduced in February 1954, the original models were 4-or-4.5-tonne (8,800 or 9,900 lb) trucks (BA and FA respectively) on a 4,150 mm (163 in) wheelbase.

[1] Visible changes vis-a-vis the earlier BX and FX trucks were mainly limited to a new grille, but the 3878 cc (236.7 cu in) F engine in the FA was upgraded, gaining ten horsepower for a total output of 105 PS (77 kW) at 3000 rpm.

The heavier FA sold very well in a changing Japanese trucking market which was moving to larger loads and greater distances.

[2] Accordingly, in September 1954 Toyota lengthened the FA's chassis and upgraded it to carry 5 tonnes, renaming it the FA5.

Also in February 1956, the FA5 was facelifted with a wider grille and equipped with a transmission with synchromesh on second through fourth gear (a first for the segment in Japan) and renamed the FA60.

[3] The heavier part of the F-engined range was split into two in September 1959, with the FA80 and FA90 being built to handle 5 or 6 tonnes (11,000 or 13,000 lb) respectively; these model codes were again maintained until the first generation was replaced.

The all new "D" engine was a pre-combustion diesel straight-six displacing 5890 cc (359 cu in) and producing 110 PS (81 kW) at 2600 rpm.

In late 1959 the lineup was refreshed and the grille was changed to incorporate two yellow marker lights.

In late 1961 (for the 1962 model year) the range was facelifted again, with a single-piece curved windshield replacing the earlier split unit.

With the sales of bonneted trucks slowing down in Japan at this time, reflecting ever more congested city streets, Toyota developed a 4-tonne (8,800 lb) cab-over version on a 3,400 mm (130 in) wheelbase.

[5] Based on the medium-duty FC80 model, the new DC80C was presented in October 1963, fitted with the D-type diesel engine and a tilting cab.

These moves were intended to make the truck a more capable proposition on Japan's newly developed highways.

TAM built a dedicated plant for the FA/DA in 1973 and exported SKD kits to various countries, including Nigeria and Australia.

They sit on a 4,300 mm (169 in) wheelbase and were introduced in September 1964; the DA115C received the enlarged 2D diesel engine with 130 PS (96 kW).

There are also period brochures from 1963/1964 showing a 5.5-tonne (12,000 lb) model called the DA95C, using the 2D engine and a version of the DA115C cab with unusual additional small windows flanking the grille.
