Can I use only Roman characters to search Japanese language materials?

By placing a "$" symbol in front of Roman characters used for search values, you can convert the Roman characters into Katakana characters to perform a search.

  • Writing in the official Kana romanization system and the Hepburn system is supported.
  • The Roman alphabet doesn't correspond to the long vowel character. For example, please enter "$kiwado" not "$kiwado" when you want to get the same result in the "キーワード."
  • _ means a blank.
