  We propose a large-scale hologram calculation using WAvelet ShrinkAge-Based
superpositIon (WASABI), a wavelet transform-based algorithm. An image-type
hologram calculated using the WASABI method is printed on a glass substrate
with the resolution of $65,536 \times 65,536$ pixels and a pixel pitch of $1
\mu$m. The hologram calculation time amounts to approximately 354 s on a
commercial CPU, which is approximately 30 times faster than conventional
methods.
