abstract = {{The SuperKEKB accelerator is a positron-electron collider with a nano-beam scheme and continues to achieve the world’s highest luminosity for the production of B meson pairs. The luminosity performance has been improved by the full-scale adoption of the crab-waist scheme. The nano-beam scheme allows the vertical beta function at the interaction point to be much smaller than the bunch length. The vertical beta function and the beam size at the collision point are the smallest in the world among colliders. As the result, the peak luminosity of 4.65 x 10³⁴ cm⁻² s⁻¹ has been achieved with the Belle II detector in 2022. Recent progress will be presented, and then the problems and issues to be overcome from the beam physics point of view will be discussed for further improvement of luminosity performance in the future.}},
