How the shape formed
This spelling combines ビ + ャ; the second character is a small kana. It represents one contracted sound in modern spelling.
History and change
Japanese writers used Chinese characters for their sounds. The source character 比 belonged to that wider practice; the kanji meaning was not inherited by ビャ.
Hiragana and katakana developed as Japanese syllabaries in the early Heian period (794–1185). This is the script-level period, not a first attested date for ビャ.
Katakana commonly writes loanwords, names, onomatopoeia, species names and visual emphasis.
What is documented?
