じゃじゅじょ — The J Row
Why the J yōon?
The J yōon group is grammatically loaded and dense in vocabulary — the second of the diacritic yōon (SH + ゛). じゃ is one of the most-used kana sequences in spoken Japanese: じゃ contracts では (\"as for\") in casual speech, じゃない is the casual negative copula (\"isn't / aren't\"), and じゃあ opens and closes conversations (\"well then\"). じゅ anchors 十 (juu, "ten") and all its compounds, 授業 (jugyou, "class"), 自由 (jiyuu, "freedom"), 重要 (juuyou, "important"). じょ is the densest in Sino-Japanese vocabulary: 上手 (jouzu, "skillful"), 女性 (josei, "woman"), 情報 (jouhou, "information"), 状況 (joukyou, "situation"), 冗談 (joudan, "joke").

What's next
After J, the next diacritic yōon is びゃびゅびょ (BY — B + small ゃ/ゅ/ょ). It's the HY (ひゃ/ひゅ/ひょ) yōon with the dakuten ゛. BY anchors 三百 (sanbyaku, "three hundred"), 病気 (byouki, "illness"), 病院 (byouin, "hospital"), and the everyday adverb 美容 (biyou, "beauty"). After BY, the final yōon is PY (ぱ row + small kana) — the very last set in the chart.
