Is this underpass easy to reach from Hirai Station?

Yes. It is just south of JR Hirai Station and only a short walk from the station exit, making it one of the easiest Takopi's Original Sin spots to visit.

Can I take photos here without causing trouble?

You can photograph the location from public space, but this is an active road and pedestrian underpass, so avoid tripods, do not stand in the roadway, and keep clear of commuters.

What is the best time to recreate the anime atmosphere at this spot?

Late afternoon, cloudy weather, or the quieter hours outside rush periods work best, because the under-bridge shadows feel closer to the anime than bright midday conditions.

takopis original sin hirai station south railway bridge underpass bridge

Walk: 3 minutes on foot
Best time to visit: Late afternoon or overcast daylight for the closest mood to the anime scene
Crowd level: Moderate

Shizuka and Takopi stand beneath the railway bridge near Hirai Station, framed by the dim underpass and a tense, emotionally heavy atmosphere.
This moment appears during one of the story’s increasingly oppressive phases, when Shizuka and Takopi are both caught in a reality that can no longer be easily undone. The cramped, oppressive space beneath the railway bridge mirrors their inner loneliness, helplessness, and confusion. Around this point in the plot, Shizuka is already under immense psychological strain, while Takopi, despite desperately wanting to make her happy, is beginning to realize that each attempt to intervene only pushes events further out of control. The location becomes more than just a place along their route; it feels like a passage into the emotional low point of the story, filled with anxiety, pain, and the sense that an even greater turning point is close. In real life, this spot lies beneath the railway bridge on the south side of Hirai Station, and the composition matches the anime remarkably well. The depth of the underpass, the looming rail structure, and the placement of the road and guardrails all make the real-world model easy to recognize. The anime heightens the mood with darker lighting, heavier colors, and a more claustrophobic feel, while the actual location looks much brighter during the day. Signs and smaller details are simplified or altered in the anime, whereas the real site includes ordinary traffic signage, railway facilities, and everyday urban clutter. Overall, the scene recreation is highly accurate, and fans can clearly compare the bridge structure, road alignment, and south-station surroundings with the anime, though visitors should remember it is an active public passage and avoid blocking pedestrians or traffic.
