How to say "similarly" in Japanese

• 同じくおなじくCommon
  adverb, conjunctionCovers 'similarly' and 'likewise' in the everyday sense of doing or being the same as something just mentioned. A common, safe choice when matching a preceding statement or person.
  私は空そらを飛とべないのと同おなじく泳およぐこともできない。↗

  I can no more swim than I can fly.
• 同様にどうように
  adverbCovers 'similarly' in the sense of 'in the (exact) same way' or identically. Somewhat less common and a bit more formal in feel than 同じく, suiting careful comparisons.
  あなたと同様どうように彼かれも大変たいへん親切しんせつだ。↗

  You and he are both very kind.
• 等しくひとしく
  adverbListed as 'similarly', but its core sense is 'equally; evenly; alike'. It fits when things are treated or shared equally rather than when an action is done in the same way, so it is often not the word you want.
• かくいう
  expressionListed as 'similarly', but it really means 'in this way; along these lines', pointing to what follows or has been described. It is usually written in kana and is only a marginal way to express 'similarly'.

Use 「同じく」 or 「同様に」 for 'in the same way'; 「等しく」 leans toward 'equally'; 「かくいう」 really means 'in this way' and only marginally covers 'similarly'.
