  Before the arrival of this skyscraper, all the buildings in the city stood in special relationship to each other.
• 羽化うかCommon
  noun, suru verb, intransitive verbThe technical term for the emergence of insects — an insect emerging and growing its wings, eclosion in English. For this biological sense it is the word to use; otherwise it does not fit.
• 台頭たいとうCommon
  noun, suru verb, intransitive verbEmergence in the sense of rising: a movement or power gaining prominence and rearing its head. The nuance is of something rising rather than simply appearing.

  Russia had emerged as a second superpower.
• 現出げんしゅつCommon
  noun, suru verb, transitive verb, intransitive verbA synonym of 出現, meaning the appearance or emergence of something. Since 出現 covers this same ground as the default choice, this word is seldom the one learners need.
• 登場とうじょうJLPT N2approx.Common
  noun, suru verb, intransitive verbEmergence as an appearance on the scene — a product arriving on the market, a new player or issue stepping into the picture. The image is of something taking the stage.

Use 出現 for the general appearance of something new, 羽化 for insects emerging, 台頭 for movements gaining prominence, 登場 for arrivals on the scene or market, and treat 現出 as a synonym of 出現.
