Tama Tech Motopia - The Weirdest Park In A Country Of Weird Parks - Part 2

Best Topic Starter
Howdy All

Tama Tech is a park that’s intrigued me for decades, I remember first coming across some of the rides in the early 2000s and being fascinated by the weird and wonderful rides.
Having done so much research on it I felt it would be nice to collect the info and my musings somewhere. So here we are

I originally wanted to just write one long post but time constraints (Damn adulting) and the sheer amount of interesting stuff means I'm going to spread it over a few days. So heres part 1.

As always all mistakes are mine and mine alone. And I apologise for the quality of some of the image. Old Japanese park stuff is often neigh on impossible to find and many rides later in these posts will have just 1 image.

The Park

Owned by a subsidiary of Japanese car company Honda the park was an insane maze of tracked rides criss-crossing over a huge valley. Obviously with the parks owners the park was themed to all sorts of motor sports and feature a constantly changing ride lineup of weird and wonderful go karts, monorails, log flumes and coasters.

Opening in 1961 and located only about 10km west of Yomiuri Land in west Tokyo, Japan the park was hugely popular in it's early years, with several smaller rides and the park hosting events such as motorcross races.

But as with many Japanese parks attendence began to decline and the financial crisis only made things worse, finally after years of making a loss the park shut its doors in 2009.

I won't delve too deeply into the history of the park with this post as I mainly want to focus on the parks unique rides over the years so lets dive in with the main reason we are all on this forum in the first place. The Roller Coaster.

Honda Sleigh / Jet Sleigh / Canadian Jet Rider

1 - Honda Sleigh

As the names suggest this is a ride that lived many lives.
Opening in 1978 and going under the name Honda Sleigh the ride originally had single automobile shaped cars holding 2 people at a time.

A single car ascends the landscaped lift hill

The coaster track would be considered tame by todays standards but it was essentially an early terrain coaster with swooping corners that kept close to the ground and an extremely low riding position.

The ride was essentially a terrain coaster, barely leaving the ground along the hillside

I actually am not sure how this version of the ride was powered to the top of the lift, It doesnt appear to have a chain on the lift hill and god knows where the anti roll backs are.

2 - Honda Sleigh

Later on its life the ride became the Jet Sleigh, I don't believe the ride changed layout but the train certainly changed. The single automobile cars were gone, replaced with a much higher capacity futuristic rocket like train with 3 cars . Capable of holding 12 guests in 2 cars of 6 and 1 driver in the front car.

Why does a roller coaster need a driver do you ask?
For an explanation i will give you this quote from Junichi Yamanaga former engineer on the ride from Honda Around The World on FB

In the past, there was Tama Tech, a facility run by Honda Land, a Honda subsidiary, that mainly sold engine-powered vehicles.
There was a motorized roller coaster there called the Honda Jet Sleigh.
While regular roller coasters rely on an external source of power to go uphill, this roller coaster is self-powered and goes uphill.
It used a car engine as its power source.
At that time, four-wheeled automobiles were not yet being produced, so I went to Midoricho in Kameido to buy a second-hand engine and installed it.
We worked through the night to install it in time for Golden Week.
No one rides the first test because it's scary.
So, as the head of development, I was the first to ride it.
When you drive, there is no steering wheel, so you only operate the accelerator and brake.
As soon as we left the station, we felt like we were climbing a wall with a 30 degree incline.
Once you climb it, you will fall under your own weight.
I was really scared at that time.

Thats right, the train was powered by a petrol engine to get to the top of the lift hill.

Once the car reached the top of the lift it would coast like a normal coaster back through the layout to the station

Another post on FB by Michio Itoh remembers that some drivers would gun the engine around the course to build up speed

Not only did it fall naturally from the top of the hill, but some drivers accelerated even harder on the way downhill, making the kids scream.

However, this was not to be the final iteration of the ride.

3 – Canadian Jet Rider
The 3rd and final iteration of the coaster would bring the ride more into line with what we expect from a coaster to this day, Replacing the petrol engine powered train with a standard chain lift and completely retracking the layout with more modern tubular steel track.

I can only imagine this was somewhat less of a maintenance headache 🤣
The ride in this configuration carried on running right up until 2005, just 4 years before the park closed.

Here's a short video clip of the ride running

Wild River Adventure
Next up is the parks unique log flume which spread across the whole valley.

Water1.jpg
The ride featured twin side by side drops

As log flumes go it wasn’t particularly tall at 11m but at 510m long it was one of the longer ones in Japan. Featuring an impressive 4 drops its undoubted party piece was the rotating water wheel lift system to take riders up to the top of the final drop. A trick I don't think we've seen repeated since?

Water2.jpg

Water3.jpg
Logs could engage the rotating lift from either side

The video below shows a view from the nearby snail monorail (Another tracked ride) which weaved around Wild RIver Adventure, It shows the water wheel and the drops very nicely


A very short clip from a TV advert also shows the water wheel and splashdown



Overview.jpg
This overview shows the layout nicely. Featuring a rotating station and 4 drops of various sizes.

The ride was only open for a short 8 years from 1996 to 2004 (another one that I assume cost an arm and a leg to operate) but seems to be fondly remembered by the locals.

Overview2.jpg
By the time the park closed in 2009 the log flume was long gone.

I wanted to write more today but its the end of my shift so Part 2 – Coming Tomorrow (Probably) featuring UFO’s, Off Road Go Karts and weirdly banked car rides.

I've been on here too many years, and have spent probably 20+ years scouring rcdb/ YouTube for unknown coasters and I've never seen this place. Thanks for the write-up looked genuinely innovative and a shame it didn't make it past 2004.
 
Onto part 2. but first Note - In researching today I found to great videos of the Water Wheel from the log flume in Part 1, I shall shortly be adding these to the original post so take a look if you missed them yesterday

We'll start with what could be considered the parks 2nd coaster, The RCDB doesn't classify it as such but I think there's a good argument to count it.

Tire Car / UFO

Another ride that has had 2 lives but unlike the Honda Sleigh this one only really changed the cars

1 – Tire Car

Opened in the 1971 Tire Car was an early type of spinning coaster. However, Instead of just relying on forces to rotate the car there was an enormous tire around each of the cars which would engage with barriers around the edge of each corner to use friction to spin the riders.

Tire4.jpg
The ride opened with this weird curved lift hill

Tire3.jpg

Later on in it's life Tire Car was upgraded to 2 car trains. In the below image you can see the barriers which caused the ride to spin.

Tire1.jpg
Seems you can get an awful lot of people in each of these cars

The ride featured sections both above ground and ones that ran along a concrete path at ground level. Both the above and below pictures show some of the above ground sections, but images are almost impossible to find due to its placement in the trees. (and it being Japan)

Tire2.jpg
It seems at opening it ran single cars too

2 – UFO

In 1980 the ride gained new 3 car UFO themed trains and a new lift hill while keeping the same basic layout

UFO3.jpg
The new straight lift hill, I assume once again this was less of a maintenance nightmare

UFO1.jpg
The new UFO themed trains in roughly the same spot as the tire car image before.

Instead of using an entire tire each car it appears the trains now spun more freely like a traditional spinning coaster.
You can watch this short clip of the ride in action and decide if you think it deserves coaster status.


Unfortunately the ride never made it to the closure of the park, closing sometime in the late 90s or early 2000s. By 2009 all that was left were the concrete trackways from the bottom end of the ride.

ACRO-X

One of the weirder rides at Tama Tech was Acro-X. While not quite unique as a couple of these were installed elsewhere, it's certainly a unique to Japan kind of thing.

Acro-X involved boarding a kind of off-road golf buggy and driving round what was essentially an assault course

The ride featured such excitingly named sections as the "Tunnel For The Brave" and the "Rattly Bridge" and of course the large (if slow) drive down into the water splash at the bottom. where various fountain effects would get you wet.

The Rattly Bridge, Which like a bridge in a fun house pivots up and down depending where the car is.

But perhaps the most interesting aspect of the whole thing was the ride had a scoring system, you could score points by hitting specifically placed bumps in the road, and you would lose points by crashing into the sides of the course.

By all accounts the buggys handled fairly poorly so avoiding the sides wasn't as as you might think

Hitting these lumps would gain you points

Don't Crush!

You can watch the entire introduction video for the ride here (Which a lot of these screens are taken from)


Perhaps my favourite moment of the intro is this exceptional piece of advise

Do not show displeasure


Skating Car

They are go karts on an Ice Rink.
Not much more to say about this one, its just cool

SkatingCar.jpg
We've all wanted to give this a go reallyI

IcrRInk.jpg
Even Mascots are allowed fun

SkyRider

Probably one of the more normal rides this one but before we being lets watch this excellent commercial for Sky Rider


This ride was essentially a monorail crossed with one of those rubbish Maurer Spike things.


Speeder1.jpg
The ride cars were themed to futuristic motorbikes

The ride ran across the valley and ran along both edges, crossing over many paths and rides underneath, and through the log flume when that existed

Like all the rides in the park it seems it was designed for kids to enjoy with adults

Here's a full POV of the ride as it was in 2009. The ride is looking a bit tired by this point.


not the most exciting ride by any means but when included in the many many more tracked rides the park had they all combine to something truly weird in my opinion

Hopefully i can get to Part 3 tomorrow. Still plenty to come

I love the idea of a modern-ish Virginia Reel and the theme is actually kind of fantastic. The curved lift is fascinating just because there doesn't seem to be a reason for it beyond just that they could. Guessing that came back to bite them at some point with the revisions. Amazing park regardless, though.
