How to say "novelty" in Japanese

• 新味しんみCommon
  nounNovelty as a quality: the freshness, originality, or newness of a work, design, or plan (the word can also refer to fresh taste). Use it when asking whether something offers anything genuinely new.
  新期しんきにスタートしたテレビ番組ばんぐみだが、あいも変かわらず新味しんみがないな。↗

  The new season's T.V. programs are as much old hat as ever.
• 変わり種かわりだねCommon
  nounA novelty as a thing, not a quality: something out of the ordinary, an unusual variant or exception. This is the word for a curiosity or oddity, not for abstract newness.
• 新しんJLPT N1approx.Common
  nounNovelty as sheer newness: the state or fact of being new. It is an abstract noun without the freshness-or-originality flavor of 新味, so it suits contexts where only newness itself is at issue.

Use 新味 for novelty as the freshness or originality of a work, design, or plan, 「変わり種」 for a novelty as an unusual thing or variant, and 新 for novelty as sheer newness.
