Nippori-Toneri Liner Hits 177% Congestion — Worst in Japan for 5th Year Running, 5ch: ‘The Real Problem Is No Demand in the Reverse Direction’

From our other sites

The story

The thread kicks off from an article reporting that the Nippori-Toneri Liner’s congestion rate hit 177%, the worst in the country for the fifth year running. The original article laid out three barriers explaining why “just add more trains” doesn’t work, but posters on the thread kept circling back to a structural problem rather than the technical constraints (the limits of keeping cars light on rubber tires, and the difficulty of adding service given its driverless automated operation): there’s almost no demand in the reverse direction during the morning rush, so running more trains wouldn’t pay off anyway. The thread also lit up over the contrast between Europe, where pouring tax money into public transit is taken for granted, and Japan, where that’s avoided, plus regional banter about riders commuting in from Chiba and Saitama.

Sh… the Toneri Liner… (trailing off, as if lost for words)
5AnonymousSep 27, 2026 12:52
Hurry up and extend it all the way to Saitama already

Re: #3
Poor guy, never made it past high school.
Re: #5
It already runs right up to the edge of Saitama.
If you want it extended, go petition Saitama.
8AnonymousSep 27, 2026 12:53
Wasn't the old Chuo Line running something like 400% back in the day?
105AnonymousSep 27, 2026 15:44
Re: #8
The old Chuo Line packed you in so tight front, back, and sides that you could seriously float in midair lol
186AnonymousSep 27, 2026 22:24
Re: #8
Go ahead and try that.
It's not possible.
9AnonymousSep 27, 2026 12:53
That's because all the country bumpkins from Chiba come flooding in
15AnonymousSep 27, 2026 12:55
Re: #9
Isn't that more the Saitama bumpkins' turf, if anything?
48AnonymousSep 27, 2026 13:36
Re: #9
No need for some hick who can't even read a map to punch above his weight and jump into the conversation
18AnonymousSep 27, 2026 12:57
Well, new transit systems like this get built more to cut construction costs than to actually move people
55AnonymousSep 27, 2026 13:49
Re: #18
Classic case of 'buy cheap, pay twice.'
19AnonymousSep 27, 2026 12:57
This country just loves packing people in like sardines

Re: #19
As long as they can't raise fares, that's the only option they've got
74AnonymousSep 27, 2026 14:41
Re: #19
That's just Tokyo for you ("Tonkin" — a mocking nickname for Tokyo)
26AnonymousSep 27, 2026 13:03
They keep whining 'can't be done, can't be done' because running it packed to the gills is the most profitable option.
Not doing anything is the right call.
Don't like it? Don't ride.

Re: #26
The thing is, the Nippori-Toneri Liner isn't even profitable despite that — that's one of its biggest problems.
There's no demand in the reverse direction.
The Utsunomiya LRT (branded "the Light Line") is the flip side — it nailed reverse-direction demand and became a huge success.
71AnonymousSep 27, 2026 14:36
Re: #26
Basically true, but leaving passengers stranded on the platform is a real problem too
27AnonymousSep 27, 2026 13:04
A line that short, buses would do just fine
31AnonymousSep 27, 2026 13:07
Re: #27
The Toneri Liner has no driver.
These days, switching it over to buses would actually be the harder option
44AnonymousSep 27, 2026 13:32
Re: #27
There was originally nothing but buses out there anyway
28AnonymousSep 27, 2026 13:05
No demand in the reverse direction means no investment.
So just move Ueno Zoo out to Toneri, problem solved
140AnonymousSep 27, 2026 19:24
Re: #28
There are already people riding it out to see the nemophila flowers at Toneri Park
36AnonymousSep 27, 2026 13:10
Re: #22
Funny how overseas, these kinds of urban lines run half-empty with a flat fare of like 50-100 yen no matter how far you go lol
134AnonymousSep 27, 2026 18:23
Re: #36
That's because it's public transit.
In Europe, it's widely seen as a citizen service.
So spending tax money on that kind of service is just taken for granted.
152AnonymousSep 27, 2026 20:31
Re: #36
In developed countries, subsidizing public transit with tax money is the norm.

Japan's just different.
73AnonymousSep 27, 2026 14:41
Just rip the seats out and make everyone stand, you'd fit way more people
75AnonymousSep 27, 2026 14:43
Re: #73
There are lines that do that.
Some fold the seats away during rush hour
76AnonymousSep 27, 2026 14:43
Re: #73
Apparently if you pack it full and it gets too heavy, it can't run
85AnonymousSep 27, 2026 15:02
Re: #73
Since it runs on rubber tires, apparently if you pull the seats and cram it full, the tires would literally blow out.
There's also a limit to how light they can make the cars.
81AnonymousSep 27, 2026 14:56
This got exposed during COVID:
Tokyo's rail network only works on the assumption that rush hour trains run packed.
The moment ridership thinned out, they cut the number of trains.
Everything else is just an excuse.
83AnonymousSep 27, 2026 15:00
Re: #81
Exactly, aiming for under 100% ridership is nothing but a fantasy.
Though I guess that's because they set commuter pass fares assuming 200% occupancy in the first place.
136AnonymousSep 27, 2026 18:28
Re: #81
And here they were complaining that if it weren't for rush hour, they wouldn't need all this equipment investment
111AnonymousSep 27, 2026 16:02
Just raise the fares already, for starters
130AnonymousSep 27, 2026 17:14
Re: #111
Exactly.
Jack the price up enough and nobody will ride it anymore
131AnonymousSep 27, 2026 17:31
Re: #130
Raise it any more and the Toei one-day pass would end up cheaper lol

Background and Key Points of the Debate

The congestion rate is a figure Japan’s Ministry of Land, Infrastructure, Transport and Tourism publishes every year, showing the ratio of passengers to a train’s rated capacity. 100% means every seat and strap is taken; around 180% is considered the point where you can no longer comfortably read a newspaper or magazine and can barely move, and 177% sits just below that line. The Nippori-Toneri Liner is an Automated Guideway Transit (AGT) system that runs on rubber tires instead of rails and operates driverlessly, designed on the assumption that its cars stay light and small — which makes it hard to add cars or beef up the trainsets the way a conventional railway can. The argument that got the most support in the thread was that demand skews heavily toward the city center in the morning and toward the suburbs in the evening, leaving the reverse direction nearly empty — so investment in more service or longer trains is hard to recoup. In other words, posters framed it less as a simple shortage of equipment and more as a problem baked into the line’s profit structure. Meanwhile, opinions split between those who felt public transit should be tax-subsidized as in Europe, and those taking a more self-responsibility line — if it’s not profitable, that’s just how it is, and if you don’t like it, don’t ride — with no clear consensus reached.
