The address is mostly correct,
but the name of this district is now Kōnanchō Fukawa (#).
Google Maps shows this elementary school as Shogakko in Japanese.
"Shogakko" (with two "o" pronounced long) means elementary school.

Japanese long-pronounced "o" is indicated in various ways
: "ō" (= "o" and a macron), "ou", simply "o", etc.
(#) This district seems to have been Fukawa of Kōnan Town [Kōnanchō]
before Kōka City was established (on October 1 in 2004)
through the merger of five Towns;
since then this district is Kōnanchō Fukawa.
Such changes in the place names (due to a merger of municipalities)
occurred here and there in Japan in recent two decades.
