<p>Since Japanese composition seeks to avoid spacing between characters as much as possible (see also JLReq <a href="https://www.w3.org/TR/jlreq/#principles_of_arrangement_of_kanji_and_kana_characters">section "Principles of Arrangement of Kanji and Kana Characters"</a>), ruby annotations wider than their base characters are not allowed to overhang neighboring kanji, but often <em>are</em> allowed to overhang neighboring kana.
This method works well when characters preceding and following
the ruby base are both kana
or both kanji.
However, depending on the number of ruby characters, it can lead to an unbalanced look when kana is on one side and kanji is on the other.

ruby annotations wider than their base characters are not allowed to overhang neighboring kanji,
but are allowed to overhang neighboring kana in some placement rules.
Such rules could work nicely when preceding and following characters are both kana or both kanji,
but it can lead to an unbalanced look depends on a number of characters of ruby annotation
in cases like kana as preceding character and kanji as following character.

<p>In letterpress printing, ruby annotation layouts were adjusted on an individual basis. Some publishers had an additional
rule disallowing overhang of adjacent kana text by katakana annotations, since katakana words can be considered a separate unit.
For such cases, depending on the length of the ruby annotation, it would produce better balance to disallow overhanging of kana characters
(see [[[#ruby-overhang-group-kana]]], where the second example applies this method).</p>

<p>To produce better balance on above cases, additional rules are required.

In some cases, an additional rule is added to disallow overhang of adjacent kana text when characters of ruby annotation are katakana,

(In fact, it would produce better balance to disallow overhang of adjacent kana depnds on a number of characters of ruby annotation.

Additional rule is also required for this point.</p>

<p>Applying one simple rule to disallow overhang of adjacent any character including preceding or following kana works
to prevent these complexity, although this rule breaks a condition to avoid spacing between characters as much as possible.</p>
