One of the most common expressions for saying something "takes time" in Japanese. The verb かかる here means "to require" or "to cost" (time, money, effort).

COMMON PATTERNS:

  • 時間(じかん)がかかる — it takes time
  • 時間(じかん)がかからない — it doesn't take long
  • どのくらい時間(じかん)がかかりますか — how long does it take?
  • 〜に時間(じかん)がかかる — it takes time for ~
  • (おも)ったより時間(じかん)がかかった — it took longer than expected

SPECIFIC DURATIONS:

SIMILAR EXPRESSIONS:

  • 手間(てま)がかかる — to require effort/trouble (focuses on labor rather than time)
  • 時間(じかん)(よう)する — to require time (formal/written)
  • 時間(じかん)(つい)やす — to spend time on (emphasizes the spending of time)

USAGE:
Note the particle が (not を) before かかる. This is because かかる is an intransitive verb — time "falls upon" the activity, rather than someone spending it.
