How to say "circulation" in Japanese

• 循環じゅんかんJLPT N2approx.Common

  Thus money in circulation drops, and price escalation quietens down.
• 血行けっこうCommon

  Moderate exercise stimulates the circulation of the blood.
• 通用つうようJLPT N2approx.Common
  noun, suru verb, intransitive verbCurrent, accepted use of a language, currency, or similar — words everyone understands, or banknotes that pass as legal tender. For circulation it covers things being in force or in common use, rather than physical movement.
• 流布るふCommon
