When the third-generation Toyota Prius was released in Japan a month ago, Toyota’s sales target for the month was 10,000 vehicles. Actual orders reached 180,000!

The Prius was the top-selling vehicle in Japan in May – the first time that it has achieved the top spot. Honda’s hybrid Insight, released in February, was the third best selling vehicle.

The new Prius is selling for just over two million yen (about $au26,000) in Japan; the Insight is 1.89 million yen ($au24,500). Toyota is also selling the previous model Prius for the same price as the Honda Insight. Sales of the old model are not included in the 180,000 orders.

Hybrid vehicles are now free of sales tax in Japan, saving about $au2,000.
