Auto-show season continues with the 2015 Tokyo Motor Show, which featured a number of notable green-car debuts.

Tokyo usually boasts a few significant world launches from the local carmakers, mixed with more esoteric models designed primarily with Japan in mind.

Hydrogen fuel-cell vehicles seemed to be prominent this year, with the introduction of the Honda Clarity Fuel Cell, as well as luxury fuel-cell concepts from Lexus and Mercedes-Benz.

Electric cars and hybrids were represented as well, and "autonomous driving" was a phrase repeated often in the press materials this year.

Without further ado, here are the significant green concept cars and production models from the 2015 Tokyo Motor Show.

The production version of Honda's hydrogen-powered car will be called the Clarity Fuel Cell.

With styling and design language that were previewed by two previous concepts, it will go on sale in Japan early next year, and the U.S. sometime after that.

The Clarity Fuel Cell is a mid-size sedan with seating for five, with both the fuel-cell stack and electric motor housed in the area under the hood. Hydrogen storage tanks are situated under the rear seat and between the rear wheels.

The electric drive motor powered by the fuel cell is rated at 174 horsepower, and Honda projects a range of 435 miles on the Japanese testing cycle.

Expect that to be closer to 300 miles on the U.S. EPA cycle.

There have also been reports that Honda will use the Clarity's underpinnings for previously-announced battery-electric and plug-in hybrid models, both of which should appear by 2018.

The LF-FC is a large hydrogen fuel-cell luxury sedan that may preview the next-generation Lexus LS.

Its powertrain components are spread throughout the chassis, with the fuel-cell stack at the back, and hydrogen tanks farther forward. Lexus says this improves weight distribution.

All of that is housed in a "four-door coupe" body that should still yield a fairly spacious cabin.

It's possible Lexus will offer a hydrogen fuel-cell powertrain option on the next LS, but Toyota's luxury brand hasn't confirmed anything yet.

Mercedes-Benz Vision Tokyo Concept

Perhaps trying to play off Japan's preoccupation with vans, Mercedes brought an autonomous fuel-cell van concept to Tokyo.

The Vision Tokyo concept echoes the radical F 015 unveiled earlier this year in technology and styling, with self-driving capabilities but a somewhat blunter and more bulbous shape.

For propulsion, the concept actually relies on both a fuel-cell stack and a lithium-ion battery pack, which can be charged by plugging in.

Mercedes says the Vision Tokyo can travel 120 miles using only the battery pack, and 600 miles on both battery and fuel-cell power.

Mitsubishi has emphasized plug-in hybrid crossovers lately, but its Tokyo Motor Show concept features an all-electric powertrain.

The eX uses one electric motor to power each axle, with energy supplied by a 45-kilowatt-hour lithium-ion battery pack.

Total system output is 187 horsepower, and Mitsubishi says the range is 248 miles on the Japanese testing cycle.

This small crossover likely previews the styling of the next Mitsubishi Outlander Sport, which will debut next month at the 2015 Los Angeles Auto Show.

Over the next few years, Nissan will unveil a redesigned second-generation Leaf electric car and an autonomous production vehicle. The IDS concept may offer some hints at both.

It is capable of fully-autonomous driving, but still offers the option of manual control. It can also learn an owner's driving style and imitate it.

The powertrain includes a 60-kilowatt-hour lithium-ion battery pack--much larger than either of the two packs offered on the current Leaf, but targeting a range of 200 miles.

The styling may or may not be a preview of the next-generation electric car; it incorporates Nissan's latest design language into a somewhat similar five-door hatchback shape.

Nissan brought not one, but two electric-car concepts to Tokyo.

The boxy Teatro for Dayz minicar was designed specifically for "digital natives"--members of the generations that grew up with the Internet--Nissan says.

An electric powertrain suits that brief, the company suggested, as the target audience will view it as just another mobile device that needs charging.

Nissan says the tiny electric car was also designed to enable social-media based sharing of life experiences, rather than just being a tool for transportation.

Subaru unveiled the third of its Viziv-series crossover concepts, previewing a possible future hybrid crossover.

Called the Viziv Future, it uses a turbocharged internal-combustion engine to power the front wheels, and an electric motor to power the rear wheels.

This creates a "through the road" hybrid all-wheel drive system, ensuring that the Viziv Future retains Subaru's trademark feature.

Subaru may incorporate this system, or something similar, into a future production crossover--though some debate exists over whether the Viziv Future previews a new generation of XV Crosstrek, or the next Forester crossover.
