埼玉県と隣接する東京23区の西端の街であり、1985年発売のとんねるずのアルバム名でも有名（？）な成増。成増の玄関口「地下鉄成増駅」のそばにキャッシュを設置しました。ちなみに駅名に「地下鉄」のつく地下鉄の駅は、ここ地下鉄成増駅と、隣駅の地下鉄赤塚駅の2つだけです。
Narimsu is the most west town in Tokyo 23 wards next to Saitama prefecture and famous(?) for the album title by TONERUZU, which were released in 1985. This cache is located just close to "Chikatesu Narimasu" station which is a door to Narimasu town. Just for mere information, there are only two metro (= "chikatetsu" in Japanese) stations containg the word of "Chikatesu": "Chikatesu Narimasu" and "Chikatetsu Akatsuka" next to there.
