We report results of measurement of the unitarity triangle angle ϕ3 with B+→ D(*)K+ Dalitz plot analysis and related issues with B0 → Ds*+ π- and B0 → Ds*- K+ decay processes. The Dalitz analysis improves accuracy of the angle ϕ3 as 78.4^∘ ~+10.8^∘-11.6^∘± 3.6^∘± 8.9^∘ and the branching fractions are found to be B0 → Ds*+ π-(K-) decays are set as B(B0 → Ds*+ π-) = (1.75 ± 0.34 (stat) ± 0.17(syst) ± 0.11(B)) × 10-5 and B(B0 → Ds*- K+) = (2.02 ± 0.33 (stat) ± 0.18(\rm syst) ± 0.13(B)) × 10-5.
