  • 監視かんしJLPT N1approx.Common

  • 張り込みはりこみCommon
    nounThe stakeout sense of 'lookout': watching a place from a fixed position, typically police observing a location in wait for someone. Use this when 'lookout' implies lying in wait rather than general guarding.

Use 「見張り」 for watching or keeping guard, 監視 for close observation or surveillance, and 「張り込み」 for a stakeout-style lookout kept in position while waiting for someone.
