First Results from KamLAND-Zen 800

KamLAND-Zen is searching for the neutrinoless double beta decay of $^{136}$Xe with a 1-kiloton liquid scintillator detector. The experiment was one of the first to reach a half-life sensitivity of $10^{26}$ years, which was obtained by instrumenting roughly 380 kg of enriched Xe in a small balloon. Since then, a new balloon was constructed in order to increase the amount of enriched Xe and further improve the half-life sensitivity. This major detector upgrade finished just last year, and in January of 2019, KamLAND-Zen began taking data with nearly a ton ($\sim$750 kg) of enriched $^{136}$Xe. New results from the 750 kg data will be presented, along with an outline of future upgrades leading to KamLAND2-Zen.
