Hakone as Tokyo-3: reading Evangelion into a real volcanic valley

The train from Gōra does something that looks like a mistake. It stops on a wooded slope, the doors stay shut, and the driver walks the length of the carriage to the other end while the conductor takes the seat he just left. Then it starts again, backwards, still climbing. On the map this is the Hakone Tozan line reversing through a switchback. On screen, decades ago, this same green ridge stood in for the ground beneath a fortress city that was supposed to save the world.

The city that was drawn over a real lake

Hakone, ninety minutes southwest of Shinjuku, is the real-world site of Dai-san Shin-Tōkyō-shi (第3新東京市), the Tokyo-3 of Neon Genesis Evangelion. The show placed its armoured skyline directly over Lake Ashi — Ashinoko (芦ノ湖) — and its underground command centre in the geofront below. The buildings retracted into the water when the fighting started. What survives, once you stop looking for towers, is the shape of the land itself: the caldera rim, the twin cone of Futagoyama (二子山), the long grey scar of a volcanic valley to the north.

You do not need to have finished the series to feel the effect. The animation was faithful enough to specific ridgelines that people who have never held a Hakone map recognise the horizon the moment they step off the boat. The pilgrimage here is not a set of addresses. It is a landscape that was traced rather than invented, and then handed back to you at full scale.

The railway that reverses to climb

Getting up into that landscape is half the point. The Hakone Tozan Railway (箱根登山鉄道) runs from Hakone-Yumoto to Gōra (強羅), climbing more than four hundred metres on a gradient of eighty per thousand — the steepest adhesion railway in Japan, meaning it grips plain steel rail with no cog to help it. Because a train cannot simply drive straight up that, the line folds back on itself three times. At each switchback the crew swaps ends and the train changes direction, so you ride forwards, then backwards, then forwards again through hydrangea banks that turn the cutting blue in late June.

At Gōra the rack ends and a cable car — a funicular, properly the Hakone Tozan Cable Car — takes over up to Sōunzan (早雲山). From there the Hakone Ropeway lifts you over the ridge. The gondola crests a shoulder of the mountain and the ground drops away into steam. This is the moment the geography stops being pretty and starts being volcanic.

Owakudani, and eggs boiled black

Owakudani (大涌谷) is a live vent a little over a thousand metres up, where the 1950s eruption cycle left the hillside stripped and yellow. Sulphur hangs in the air; the ground hisses. The local trade is kuro-tamago (黒たまご), eggs lowered into the hot spring pools until the iron in the water blackens their shells — a bag of five costs around 500 yen at the vent-side stand. The story goes that each one adds seven years to your life, which is the kind of claim that survives precisely because no one can test it.

Eat one on the observation deck with the steam moving across the slope below, and the connection to the anime stops being a game of matching frames. The show borrowed this valley because it already looked like the aftermath of something. Standing in it, you understand the borrowing was almost lazy — the place did most of the work.

The lake is real. The city that stood over it never was, and that gap is the whole pilgrimage.

The gate standing in the water

The ropeway comes down at Tōgendai on the north shore of Lake Ashi, where the sightseeing boats — dressed, with no explanation anyone can give you, as pirate galleons — cross to Hakonemachi and Motohakone in about half an hour. From the water the caldera opens fully: Komagatake (駒ヶ岳) to the east, Mount Fuji behind the far rim on a clear morning, and the ridge the animators drew standing exactly where it was drawn.

At Motohakone, a short walk along the shore brings you to Hakone Shrine's Heiwa no Torii (平和の鳥居), the vermilion gate that stands in the shallows with its feet in the lake. There is usually a quiet queue for the photograph taken from the jetty; the shrine posts staff and a small sign asking people to keep the line moving, because the spot sits on a working approach to the shrine and not on a film set. It is worth the wait, and worth being brief about.

アニメの稜線は、いまも湖の向こうにそのまま立っている。

Going, and the one thing that can close

Come from Shinjuku on the Odakyū Romancecar (小田急ロマンスカー), a reserved limited express that reaches Hakone-Yumoto in about eighty-five minutes for roughly 2,470 yen all-in. The efficient move is the Hakone Free Pass, sold by Odakyū for about 6,100 yen for two days from Shinjuku; it covers the return leg plus the switchback train, the cable car, the ropeway, the pirate boats and the mountain buses, which is nearly every conveyance the loop above uses. Ride the circuit clockwise — train, cable car, ropeway, boat, bus back — and you never double back on yourself.

Go on a weekday if you can; Saturday queues at the ropeway and the boat pier can cost an hour. And the one mistake to avoid: never assume Owakudani is open. The valley is a monitored active vent, and when the volcanic alert level rises the ropeway and the walking trail close, sometimes for weeks, as they did through much of 2015. Check the current status the morning you travel rather than the night before. When the mountain is venting hard, the lake and the shrine are still there — and honestly, the ridge across the water was always the part that mattered.
