  We have performed tilted-axis-cranked Hartree-Fock-Bogoliubov calculations
for a neutron-rich hafnium isotope ($^{182}$Hf) whose proton and neutron
numbers are both in the upper shell region. We study whether the shell effects
play a role in producing high-$K$ isomers or highly gamma-deformed states at
high spin. In particular, the possibility of shape coexistence and the effect
of wobbling motion are discussed.
