No New BEVs in Chiba: Japan's OEMs Bet on Everything Else

Zero new BEV models, zero new traction batteries, zero new BEV platforms. That was the tally at Japan Mobility Show Bizweek 2026, held at Makuhari Messe in Chiba from October 13 to 16, and it tells you more about Japan's powertrain strategy than any concept car could.

The event's main banner read: "Keep moving, Japan. No single technology can move the future on its own." JAMA's central MOVE JAPAN exhibit organised the floor around six themes: multi-pathway powertrains, hydrogen adoption, joint logistics, autonomous driving, dynamic wireless power transfer, and the circular economy.

Three of those carried the real weight: multi-pathway, hydrogen, and AI-driven automated driving. The BEVs that did appear were test cars for AI software or props in charging and energy-storage demos. Not headline acts.

What did the engine makers bring?

Almost all the hardware under the multi-pathway banner was combustion-based, repurposed. Nissan showed a cutaway of its third-generation e-POWER hybrid: a ZR15DDTe dedicated engine paired with a new 5-in-1 electric drive unit, reaching 42% thermal efficiency per the display. Mazda's Rotary-EV System Concept (2 Rotor) sat directly beneath the banner — no specifications disclosed, but the display pitched the rotary as a compact generator running on hydrogen, biofuels and e-fuels, and argued against carrying more battery than you need.

Daihatsu went further into odd chemistry. It showed the first physical unit of an ammonia/hydrogen co-combustion engine: a 658cc three-cylinder Kei unit weighing about 60kg that converts part of its ammonia into hydrogen on board. The company listed its own hurdles honestly — NOx, unburned ammonia, tank safety, refuelling infrastructure — and said it's looking for partners. Suzuki, meanwhile, displayed an India-only Victoris running on CNG and compressed biomethane derived from cow dung.

The takeaway: Japan's OEMs see a long future for the combustion engine, as a generator inside electrified drivetrains and as a carrier for low-carbon fuels.

Where is hydrogen going?

Not into passenger cars, mostly. The hydrogen zone focused on production and trucks. Toyota and Chiyoda Corporation presented a water electrolysis system applying Toyota's fuel-cell expertise; the 5MW-class unit at Toyota's Honsha plant produces 96kg of hydrogen per hour, and Toyota plans mass production of electrolyzer stacks from FY2029.

Mitsubishi Fuso's H2IC Heavy Truck burns hydrogen in an engine sharing many parts with its diesel variant, delivering roughly 700km of range on one fill of its 70MPa tanks in internal testing. Japan's "hydrogen backbone" initiative targets the Fukushima–Fukuoka trunk route: the equivalent of 1,500 heavy trucks operating daily by 2035, backed by 30 hydrogen stations and a targeted price of JPY1,000/kg ($6.3/kg).

GlobalData's numbers back the commercial-vehicle logic. It forecasts Japan's FCEV light vehicle sales at just 3.6k units in 2030, up from just over 400 units in 2026. Hydrogen cars remain a rounding error.

Can AI carry the automation story?

Nissan's ProPILOT prototype, based on the Ariya, uses end-to-end AI with cameras, radar and LiDAR for door-to-door driving on complex city streets. Nissan stated Level 4 robotaxi trial operations begin in the second half of 2026, with the first Wayve-based next-generation ProPILOT model launching in Japan in FY2027.

Subaru and Toyota took the infrastructure route instead. Subaru's Levorg test car shares data with roadside units and control servers over local 5G; Toyota's ITS Smart Pole uses cameras and LiDAR to watch intersection blind spots, with trials underway in more than 20 regions. Toyota's stand had no vehicles at all — just its CUE basketball robot and the message "the world's factories are a test field." Mazda demoed an "empathetic AI" with UK startup Thymia that estimates driver condition from voice.

What about logistics, road power and recycling?

Supporting roles, same logic. Honda's DWPT display claimed 50kW per ground unit with a 200kW target for heavy trucks and expressway trials from FY2027; Japan's roadmap puts DWPT on main expressways from the early 2030s. Isuzu, Hino and UD Trucks bosses were listed for a session on connecting commercial vehicles, logistics data and autonomous control. Mitsubishi Motors showed its Battery Cube — a towable 24kWh storage unit built from three used Outlander PHEV packs — and Nissan showed closed-loop aluminium recycling.

Why the light BEV presence makes policy sense

Transport was 19.3% of Japan's CO2 emissions in FY2024, and road vehicles made up 85.6% of that. Japan targets 46% emission cuts by FY2030, 60% by FY2035 and 73% by FY2040 from FY2013 levels, backed by JPY20 trillion ($126.6 billion) in government investment over ten years through GX Economy Transition Bonds under the GX 2040 Vision updated in February 2025.

Crucially, METI targets 100% "electrified" new passenger car sales by 2035 — a definition that includes hybrids. It also wants E10 gasoline supply from FY2030, E20-compatible cars as early as possible in the 2030s, and E20 supply from FY2040. The Hydrogen Society Promotion Act adds 15 years of price-gap support for low-carbon hydrogen. This system-wide approach is where Japan diverges most from China and the EU, which put the BEV at the centre.

What to watch next

GlobalData forecasts Japan's FHEV sales at 1.48 million units in 2026 and 1.50 million in 2030, still the largest electrified segment. BEV sales grow from 147k units in 2026 to 523k in 2030 and 1.65 million in 2035 — overtaking hybrids in 2033. Japanese brands account for most of that, at 422k BEV units in 2030, up from 96k in 2026.

The risks are timing risks. Dedicated BEV debuts were absent because new models are saved for the main show in odd-numbered years — but global markets keep electrifying, and multi-pathway depends on fuels, hydrogen supply and road infrastructure that largely arrive after 2030. Some of these routes may only be ready once the BEV wave has already reached Japan. Watch the FY2027 ProPILOT launch and the 2033 BEV–hybrid crossover.
