A novel relation is found which holds experimentally very well and gives the 2-3 lepton mixing angle θ_<μτ> in terms of quark masses and CKM mixing: tanθ_<μτ> = (m_b /m_s)V_<cb>. This relation is a kind of SO(10) GUT relation similar to the celebrated bottom-tau mass ratio in SU(5), and seems to give an important clue for the final grand unified theory.
