This is beautiful. I went there 20 years ago and my mind was blown then how big it was but I really had no idea!

Can’t help but think of the 3D map of Midgar from FF7 when I look at this

Very cool and very performant

Now we just need an app that links your location in 3d space so you can finally easily navigate Shinjuku.

What are the steep angle arrows indicating? Too steep for an escalator/stairs, but not 90 degrees like an elevator would need to be. Anyone know?

Finally I'll be able to properly follow JJK season 2

looks like a doom level

They're connecting Tokyo and Nihonbashi stations underground which will effective connect 10 stations in total with underground passages so that would be another interesting 3d map Also, that map seems incomplete by at least a 3rd. The connection between it and Shinjuku-3-chome station is missing (the hallways just arbitrarily stop on that map) and the tunnels from there to the south entrance of Shinjuku station are missing as well as 3 more train platforms. I suppose you could argue that's a different station which is fine, but the fact that tunnels don't end where they appear to on this map is misleading.

Really cool, it's giving me Ghost in the Shell computer UI vibes.

I've never really had crowd fear, but after a crush event at an agricultural fair underpass, I acquired it. Shinjuku just before rush-hour brought it back on, and I basically ran away and sat under a tree for an hour or so. I've been in Tokyo and Ikebukuro at busy times, but nothing has been like Shinjuku to me. Maybe it's the escalators and a certain ordered-but-relentless ant-army mentality getting to the platforms.

This is an excellent visualization! I would love to see someone adapt this data into a first-person navigation game. The game should put you at some location in the station complex and ask you to navigate to some location. This would be excellent training for people visiting the real-life Shinjuku station for the first time.

Funny to see this as well as the Gaussian splat cathedral on the HN front page at the same time. While the Gaussian splat is impressive, I kinda still dig the wireframe…

get stuck at the center where I can't zoom or move around anywhere.

NO WONDER I've become lost in Shinjuku Station on at least 3 occasions!

very cool project. would you create more of this for other stations in Tokyo? or other famous stations on different cities
