KamLAND reports on a precise measurement of neutrino oscillation parameters with reactor ve, and an estimate of geo ve flux including the period of the recent long-term shutdown of Japanese nuclear reactors. KamLAND-Zen reports on a preliminary search for neutrinoless double-beta decay with 136Xe based on 114.8 live-days after the purification of the xenon loaded liquid scintillator. By combining the KamLAND-Zen pre- and post-purification data, we obtain a preliminary lower limit on the 0vββ decay half-life of T0v1/2 > 2.6 × 1025 yr at 90% C.L. In this article, the latest results and future prospects of KamLAND and KamLAND-Zen are reviewed.
