| Summary:
We report a determination of the CKM angle $phi_{3}$, also known as
$gamma$, from a combination of measurements using samples of up to
711~fb$^{-1}$ from the Belle experiment and up to 362~fb$^{-1}$ from the Belle
II experiment. We combine results from analyses of $B^+to DK^+, B^+to
Dpi^+$, and $B^+ to D^{*}K^+$ decays, where $D$ is an admixture of $D^0$ and
$overline{D}{}^{0}$ mesons, in a likelihood fit to obtain $phi_{3} =
(78.6^{+7.2}_{-7.3})^{circ}$. We also briefly discuss the interpretation of
this result.
