「ニイタカヤマノボレ」は「ここから送信したっぽいね」くらいの信ぴょう性だそうで。
wikiには千葉の送信所から出されたと書かれてますので、どっちだかといったかんじです。
ちなみに近くにパン屋さんがあって、そこでＵターンついでにパンを買いました。
おいしかったです。

I hear that "CLIMB MOUNT NIITAKA" has enough authenticity that it "seems like it would have been sent from here". It's written in the wiki that it was sent from a transmitting station in Chiba, so we have to wonder which it is.

By the way, there was a bakery nearby, so we made a U-turn and took the opportunity to buy some pastries.
