What is the relationship between "Fuchs du hast die Gans gestohlen" and 「こぎつねこんこん」?


There is a [German children's song](https://youtu.be/oz--4Jmnr1w?t=20) named
"Fuchs du hast die Gans gestohlen" about a fox stealing a goose. According to
[Wikipedia](https://de.wikipedia.org/wiki/Fuchs,_du_hast_die_Gans_gestohlen)
the melody comes from another song named "Wer eine Gans gestohlen hat" which
is about geese but not about foxes.

There is a [Japanese children's
song](https://www.youtube.com/watch?v=kOuoIQWlrHs) named 「こぎつねこんこん」 (judging
by the YouTube title) with a very similar melody that is also about foxes. I
found a [Wikipedia
article](https://ja.wikipedia.org/wiki/%E5%B0%8F%E3%81%8E%E3%81%A4%E3%81%AD)
that may or may not be about the song. (I don't speak Japanese.)

What is the relationship between the two versions?




The German _Fuchs, Du hast die Gans gestohlen_ is the original song. (The
modern version is due to Ernst Anschütz (1824).)

The Japanese 『小ぎつね』 (or 小ぎつねこんこん) is a version by 勝【かつ】 承夫【よしお】 _Yoshio Katsu_
, first listed in the textbook 『三年生の音楽』 "Music for the third grade" published
in 1947 by the Ministry of Education, Science and Culture.

The song is still contained in the [ministry-approved
textbooks](http://www.kyogei.co.jp/publication/textbook/h27_elementary_school/a2.html)
(now for second grade), listed as:

> 曲名： 小ぎつね、 作詞者： 勝 承夫 （日本語詞）、 作曲者： ドイツ民謡

which translates to

> _Title:_ 小ぎつね, _Lyrics:_ Yoshio Katsu (Japanese lyrics), _Music:_ German
> folk song
