We have performed a variational Monte Carlo simulation to study the groundstate of a two-dimensional Hubbard model on a square lattice in the strongcoupling region. The energy gain of possible inhomogeneous electron states arecomputed as a function of $U$ when the hole density $\epsilon=1/8$ and nextnearest-neighbor hopping $t'/t=-0.30$. The bond-centered ferromagnetic diagonalstripe state is stabilized in the strong coupling region ($U/t\geq$16), whichis due to the gain of both kinetic energy and on-site Coulomb interactionenergy due to the holon moving over the ferromagnetic domain and the gain ofkinetic-exchange-interaction energy at the antiferromagnetic domain wall.
