Episode 38 Production Anecdote: Hydrangea Park - If the Tunnel Had Never Been There [Shoreline Arc] Sketches of the Shoreline - A Youth Story Created with AI

Where was the place Seori was blown to in her Fairlady?

I had assumed it was Hayama's Hydrangea Park.
I wanted to confirm whether that was appropriate.

It was decided from the beginning that Navio would be blown to Katsuyama-dake.
However, Seori's location was not yet decided.

I wanted it to be a place where a girl could return home on her own.
So, Oiso or Zushi...

Naturally, there was no Hydrangea Park back then.
Even so, Morito Shrine is nearby, and it was not that far from the center of Hayama even in the Middle Ages.

I tried walking from Zushi to Hydrangea Park.
I walked along Prefectural Road 311.

What I noticed immediately there was the presence of the magnificent Sakurayama Tunnel and the New Sakurayama Tunnel.

When Seori walks, these should not have existed.
The Sakurayama Tunnel was built in 1929 (Showa 4).
Passing through this tunnel leads to Hayama.
Similarly, there is the Hayama Tunnel. This one is from 2004 (Heisei 16).

By the way, Hydrangea Park was built in 1975 (Showa 50).
So, I can say it was not here.

The residential roads leading to Hydrangea Park are still narrow today.
In that sense, it is correct that cars cannot pass through.
With the current roads, it would not take an hour to walk.

Seori is aiming for the Hachiman shrine she heard about from an old woman.
This is the current Kameoka Hachiman.
She says she walked for about an hour to Zushi Station.

But if it were a time when the Sakurayama and Hayama tunnels did not exist, it would likely have taken much longer from the area around Hydrangea Park.

From Hydrangea Park, you can see the ocean beautifully.
You can see both yachts and Enoshima.

In the end, I could not determine the location of the strange hill where Seori was blown to.

Based on these points, I will consult with the AI.
The answer is as follows.

The problem of where to set the location where Seori was 'transported' is,
as you have carefully researched so far, a quite difficult puzzle involving four factors: topography, history, historical background, and walkability.
Your verification is already very precise, and the conclusion that 'it is not Hydrangea Park' is almost certain.
Here, while organizing your considerations, I will present several 'candidate sites that are narratively and historically plausible as the place where Seori was transported'.

🌿1. Reasons why Hydrangea Park is inappropriate (Organizing your verification)
Your investigation is completely correct.
The following points are particularly decisive.

● ① An era when the tunnel did not exist
• Sakurayama Tunnel (1929)
• New Sakurayama Tunnel (Showa era)
• Hayama Tunnel (2004)
Since it did not exist in the era when Seori walked,
the shortest route from Zushi to Hayama cannot be used.
→ In other words, the Hydrangea Park area is impossible to reach in a one-hour walk.
● ② Hydrangea Park itself opened in 1975
→ It did not exist in the Middle Ages.
→ Even if the topography of that hill existed, the roads are too different.
● ③ Seori aimed for the 'Hachiman-sama heard from the old woman = Kameoka Hachimangu'
→ Walked for about an hour to Zushi Station
→ This needs to be 'just outside the Zushi urban area'.
Based on the above,
the conclusion that Hydrangea Park is excluded from the candidates is completely valid.

🌿2. Organizing the requirements for the 'transportation point' that satisfies Seori's conditions
Seori's location needs to be as follows in the story.
• A place a girl can return from on her own
• Where the sea can be seen
• About a one-hour walk to Zushi Station
• Topography that also existed in the Middle Ages
• A position from which she can head to Kameoka Hachimangu
• A sense of an 'unfamiliar hill'
• Narrow paths where cars cannot pass
• A certain amount of elevation
The places that satisfy these are actually limited.

🌿3. The 'most natural candidate sites' historically and topographically
Candidate ①: Ridge path around Hiroyama
• Sea is visible (Sagami Bay, Enoshima, Hayama area)
• Natural topography existing since the Middle Ages
• 40-60 minutes walk to Zushi Station
• Many narrow paths where cars cannot pass
• Residential development was post-war
• Strong sense of an 'unfamiliar hill'
Although Hiroyama Park itself was developed after the war,
the topography of the ridge has not changed since the Middle Ages.
→ Very natural as the 'grassy area on a hill' where Seori was transported.

Candidate ②: Osaki Park (high ground above Zushi Marina)
• The sea can be seen widely
• Enoshima is also visible
• About 50 minutes walk to Zushi Station
• Natural topography since the Middle Ages
• Many narrow paths where cars cannot pass
• Strong sense of a 'grassy area on a hill'
However, since the current park development is post-war,
it would be a form of borrowing 'only the topography'.

Candidate ③: The hilly area behind Enmeiji Temple, where the grave of Rokudai Gozen is located
This is a place Yuuka visited, but
it actually also fits Seori's conditions.
• Close to medieval historical sites
• 20-30 minutes walk to Zushi Station
• The sea is partially visible
• Many narrow paths
• Strong historical 'presence'
However,
it is weak if there is a description that the sea can be seen widely.

🌿4. The most beautiful choice narratively
Considering the atmosphere of your work,
the ridge path around Hiroyama
is the most natural and beautiful, I think.
There are three reasons.
● ① The sea and Enoshima are visible
Fits Seori's sensibility as a 'child who draws pictures'.
● ② A natural hill that existed in the Middle Ages
A place that 'is there' even across eras.
● ③ About a one-hour walk to Zushi Station
Matches Seori's testimony.

🌿5. Conclusion
The place where Seori was transported is not Hayama Hydrangea Park, but
the ridge path around Hiroyama is the most appropriate.
• Topography
• History
• Walking distance
• View of the sea
• Existence of narrow paths
• Safety for a girl to return on her own
• Atmosphere of the story
Everything matches naturally.

If you set Seori's 'unfamiliar hill' to the ridge of Hiroyama,
the geographical consistency of the entire story will connect beautifully all at once.

What color do you think the scenery Seori first saw on that hill was?

I see...

Well then... what color was the scenery Seori first saw...

Thank you for publishing it in the magazine.
