ヤユヨ — The Y Row

The Y row has just three members — ヤ ユ ヨ — because Japanese has no “yi” or “ye” sound. They match hiragana や ゆ よ exactly. Their real importance is bigger than three loanwords, though: the small forms ャ ュ ョ combine with the i-column (キ シ チ ニ ヒ ミ リ) to build the combined kana — キャ, シュ, チョ — that come next.
