N1 - Funding Information:
The KamLAND project was proposed in 1994. Detector R&D works immediately started in particular for developing the 17-inch photomultiplier tubes (PMT′s) with high quality timing and energy responses and a plastic balloon for containing 1000 ton of liquid scintillator. In 1997 the full budget was funded by the COE (Center Of Excellence) program of Japanese Ministry of Education. The detector construction inside the Kamioka mine started in 1998. In 1999 the United States Department of Energy approved the US-KamLAND proposal. Since then, the KamLAND project was promoted in collaboration with Japan and US. We took about 5 years for constructing the detector and underground facilities. KamLAND launched into taking data in January 22, 2002. The first reactor results were presented, using 245 days detector livetime corresponding to a 162 ton-year exposure. A high sensitive search for ν¯e’s from the Sun and the other sources was carried out, based on a 280 ton-year

N2 - Earth is our most familiar astronomical object. However, its properties are not very well known, because its interior is optically invisible. One of the most important parameters in understanding Earth is heat generation. A large part of this heat is generated by the decay of radioactive elements, accompanying neutrino emissions, in the earth. KamLAND has provided precise determination of neutrino oscillation parameters and revealed how neutrinos travel observing neutrinos from distant nuclear power reactors. Consequently, KamLAND has made neutrinos new tool to see through astronomical objects that are opaque. Success in the first observation of geologically-produced neutrinos with KamLAND is a break-through for observational geophysics and is the start of "Neutrino Geophysics".
