Toyota has announced that the Mirai fuel-cell sedan has racked up approximately 1,500 orders in Japan, a month after sales began on December 15, 2014.

The number far exceeds Toyota’s plans: at the time of the vehicle’s launch, the automaker said it expected to sell approximately 400 units in Japan by the end of 2015. Due to the large volume of orders received, Toyota is now forecasting a significantly longer time to delivery than originally expected.

About 60 percent of the orders came from government offices and corporate fleets, and 40 percent from individual consumers. Orders are mostly from Tokyo, Kanagawa Prefecture, Aichi Prefecture and Fukuoka Prefecture. The Mirai is priced from 7,236,000 yen (approximately $62,040) in Japan, including consumption tax.

In the United States, the Toyota Mirai is priced from $57,500, but Toyota says it could qualify for combined state and federal incentives of up to $13,000, in which case the purchase price would potentially drop to about $45,000. Alternatively, Toyota will offer a $499 per month/36 month lease option, with $3,649 due at lease signing.

The Mirai’s fuel cell stack system combines hydrogen gas from tanks with oxygen to produce electricity that powers a 113kW (152hp) electric motor driving the front wheels. The tanks can be refueled in about five minutes offering a range of up to 300 miles or 483 km.
