Where is that town?

Where is that town which Madoka and Hikaru-chan live in? This story is a fiction but that town may exist.

When Kyousuke moved to that town and met Madoka for the first time, Madoka pointed out Kyousuke spoke with a country accent. And the name of the amusement park where Kyousuke dated Hikaru-chan is "Toshima-en", so this model must be Toshima-en which exists in Tokyo.

From these things, I suppose that town exists around Tokyo.

Next, among the stations which appear on "KOR" , an existing station is only "Nakagawa Station". In Japan, "Nakagawa Station" exist two, one is in Yamagata prefecture, another is in Kanagawa prefecture. Suppose that town exist around Tokyo, Nakagawa Station which appears on "KOR" is the station of the Yokohama municipal management subway in the Kanagawa prefecture.

So that town must exist around this station. In other words, that town exist around Yokohama city. But one scene overturns this guess root and branch. The scene is the letter which Madoka is sending to Kyousuke from Hawaii was zoomed in. The letter said "Tokyo Japan". From this scene, that town was not around Yokohama but in Tokyo. And the telephone exchange number of disco "Moebius" was 03, the exchange number of Tokyo.

Regrettably, I could not read about the detailed name of the town on the letter. But the key which solves the question is left. When "Talent Scout Caravan" came to the town , the name of the place was "Yokuya public hall". This must be on the model of "the Shibuya public hall".

So that town which Madoka and Hikaru live in is fictitious town "Yokuya" on the model of "Shibuya".

note : Sibuya is the most suitable town for the young in Japan
