We present a search for the proton decay mode $$p \rightarrow \bar{v}K^+$$ based on an exposure of 8.97 kton-years in the KamLAND experiment. The liquid scintillator detector is sensitive to successive signals from $$p \rightarrow \bar{v}K^+$$ with unique kinematics, which allow us to achieve a detection efficiency of 44%, higher than previous searches in water Cherenkov detectors. We find no evidence of proton decays for this mode. The expected background, which is dominated by atmospheric neutrinos, is 0:9 ± 0.2 events. The nonbackground-subtracted limit on the partial proton lifetime is τΒ($$p \rightarrow \bar{v}K^+$$) > 5.4 x 10³² years at 90% C.L.
