Why wasn't 欒 simplified to 栾, when 戀 was simplified to 恋?


A few pre-simplification kanji (旧字体) that had the 䜌 "radical" in them were
simplified such that they instead used the simpler 亦 "radical" in its place,
as with 戀 to 恋, and 變 to 変.

However, 欒 (as in 団欒) does not have a simplified form (新字体) that is used in
Japanese (though it appears that 栾 _is_ used in simplified Chinese).

Is there a reason that 欒 wasn't simplified, or is it just one of those
arbitrary things for which there isn't a real explanation?




Because, in principle, Japanese kanji **simplification only affects those
in[常用漢字](https://en.wikipedia.org/wiki/J%C5%8Dy%C5%8D_kanji)**.

The 常用漢字 (originally named 当用漢字) was legislated to limit kanji usage within
it, as the first step of gradual abolition of kanji. So no regard is given to
unlisted kanjis in the first place, that is, there was no official stipulation
about the rest of kanjis. People usually just followed previous customs, while
some of them tried to apply it to all kanjis analogically (see
[朝日字体](https://en.wikipedia.org/wiki/Asahi_characters) and
[拡張新字体](https://en.wikipedia.org/wiki/Extended_shinjitai)). The ultimate
purpose of 当用漢字 was soon abandoned, and only the half-baked standard remained
under the name of 常用漢字.

Today, kanji restriction is virtually no longer desired, and

published in 2000 was seen as official discouragement against any further
simplification outside 常用漢字. Since these rules only cover printed characters,
you are allowed to write in simplified way by hand, in theory. But in your
case, 栾 looks so different with 欒 that you might have difficulty being
understood.

P.S. [This article](https://en.wikipedia.org/wiki/Japanese_script_reform)
could be a good summary to this problem in English, which I haven't read
through :)
