(Updated 3/14/2026) If you ever go to Ikebukuro in the northern Tokyo ward of Toshima, you might see one of these strange contraptions ambling about. Ikebukuro is one of Tokyo’s many “centres” – a high-concentration shopping and entertainment area always heaving with throngs of people. And now, they have a new way to get around.
The Ikebus (pronounced “Ee-kay-bus”) is another one of the many initiatives taken by various Japanese authorities and firms ahead of the 2020 Summer Olympics. The idea was to find a distinctive vehicle to focus attention on the Ikebukuro area. On that score, it’s a complete success. It’s impossible to ignore these bizarre red rectangles on the streets.
The Ikebus is strangely reminiscent of the Catbus seen in the 1988 animation classic My Neighbor Totoro directed by Hayao Miyazaki. This is probably not a complete coincidence, since Ikebukuro is the centre of animé culture in Tokyo. That being said, I don’t think the base vehicle, the eCOM-10, was designed with Miyazaki’s input…
The eCOM-10 is a ten-wheeled “low-speed community vehicle” made by Thinktogether Co., Ltd., based in Gunma Prefecture. The eCOM-10, which was developed from the smaller eCOM-8, is a battery-operated AWD vehicle. The eight- and ten-wheel EV bus concept was co-developed with Gunma University, so it’s probably some sort of private-public partnership. The Ikebus itself was designed by Eiji Mitooka, who is more renowned for his work at Japan Railways.
I guess that explains the shape of the Ikebus, making it square to maximize passenger space and completely disregard anything else. This thing is not meant for land speed records, after all. The eCOM-10’s vital statistics make for unusual reading. The rearmost wheel is the only one that doesn’t turn, it seems. Each wheel is powered by a 1.3kW motor. Top speed is 19 kph (12 mph). Wheelbase length is 499.5cm (196.5 in.) and total length is 6 meters (just over 19’6’’, or 3 in. longer than a 1977-79 Lincoln Continental). Passenger capacity: 14 seating down and seven standing. Weight (without pax): just under 1600kg – not bad, compared to the aforementioned Lincoln’s 2400kg.
I’m not 100% clear on several details – nearly all the information out there is in Japanese. One thing I did find out is that this vehicle has an autonomy of just 30km at full clip. Which means the Ikebus can only run for about 90 minutes before it needs to be recharged. Therefore, the two routes served by this bus are very short – about 35 minutes end to end.
And because it needs all the juice it has just to keep going, the Ikebus is devoid of any HVAC whatsoever. Which means that they will not be running during the summer months, when temperatures routinely reach over 35°C (95°F) and the humidity is high. So the 2020 Olympics, if they take place as scheduled (which is perhaps optimistic), will not serve as much of a showcase for our little ten-wheeler.
The Ikebus took its first paying passengers in November 2019. Last month, Thinktogether (sometimes also spelled “Thinktogather”) delivered the final three units to Willer, the operator. This gives us a grand total fleet of … ten buses. They’re all painted red, except #7 – that one is yellow. They call it the “Lucky Seven”. Is that a thing? I thought the number eight was the lucky one. Maybe that’s only in China.
Stops are identified by a big red rectangular sign. Perched atop this watchtower is the bus’s mascot – an owl with a crown, also found on the vehicle itself. Ikebukuro is associated with an owl for some reason, so that’s where that comes from. The crown is less obvious. In fact, not much about this entire thing is all that clear yet, but pleasantly left-field. Japan in a nutshell.
Random! I suppose I like the general idea, the execution not quite as much, 12mph max is nowhere near the speeds that cars and buses travel on Tokyo’s roads in general leading me to think that this may get in the way more than it should.
Perhaps range is longer if the vehicle is not actually traveling flat out all the time? With no HVAC there isn’t likely to be much draw besides when it is actually moving. Still, it’s a starting point I suppose, the next generation will likely be improved in every respect. It’s good to see a city actually build and try to improve on the (generally) already excellent public options out there.
Seems like it would be more efficient, and get more mileage per charge, without the hugely complex and heavy technology for driving and steering 10 wheels. More room for batteries. I guess efficiency isn’t the point. Ours not to reason why….
“without the hugely complex and heavy technology for driving and steering 10 wheels.”
The Japanese are very willing to embrace technology and then steadily improve it to the point it performs surprisingly well.
However, the initial approach often proves to be a dead end. Examples include the rear steer and active suspension systems developed in the eighties. Initially, they used complex and intrusive components that completely modified the system design. Now rear steer has evolved into a single adjustable suspension link, and suspension systems use variable orifice dampers (adjustable but not active).
I believe that if it were sold in numbers to the general public, it would be named the Thinktogether E-com Opaque Purpose.
It appears that in thinking together, everyone on the project at Guma Uni thought of a wheel, which was then each democratically included and ranked front to back. Or perhaps it was a three-wheeled roadster, as rendered by a committee.
At ten wheels for 14 seats, it is a rare statistic that can make that ’77 Lincoln – with a ratio four for six – look efficient.
It seems to be a creation just to Keep Ikebukuro Weird, and I don’t see the point, wheely, but I am now over-tyred, and shall depart.
Great post – a friend told me that these were now running in Ikebukuro but I haven’t made the trek to see one yet – definitely will now. They’re a little more interesting than the ubiquitous Hino Ponchos. Jim.
The low chassis with lots of small wheels would make an excellent Cat Bus
Wanted to say the same thing..
That’s precisely what this bus is channeling. The ten wheels are not necessary technically; it’s a typically Japanese playful riff on the Cat Bus.

Why do these repeat stories keep coming up? When I read the getting ready for the 2020 Olympics it lost my attention.
Because we regularly rerun most of our content after six years. This was at the beginning of the text: (Updated 3/14/2026) which makes it clear that it’s a rerun.
I’m glad it came up as I didn’t see it back in 2020.
The five axles on this thing puzzle me. Is it really THAT heavy due to (what kind of batteries and how many) that it needs to spread the weight out five ways? Tesla of 2020 managed to make their cars with only 2 axles, and the later and very heavy cybertruck doesn’t need a row of tires.
That they had to make it almost a crab configuration (all wheels turn on a crab dolly. This leaves the rear fixed) is another puzzlement. Are the wheels there for fashion, akin to 21st century tail fins?
A very bizarre vehicle that probably annoys anyone stuck driving behind it as US drivers are annoyed when they find themselves behind a school bus.
Slow with lots of stops.
There’s also the weight of a full complement of passengers to consider, and the small size of the wheels (prolly chosen to maximize cabin volume) means each one can support less weight than a larger wheel.
I was puzzled at first about the rearmost wheels not turning, until I realized that referred to steering, not rotation.
No, the ten wheels are not necessary technically; it’s a typically Japanese playful riff on the Cat Bus.

Here in Québec, we still have very conventional buses, but with the latest paint job ‘dernier-cri’, like the cry of the latest trendy Aliens
