Query: The MAHOROBA Project -- Deep Survey with an Optical Intermediate-Band
  Filter System on the Subaru Telescope   We present a summary of the new optical intermediate-band filter system for
the prime-focus camera, Suprime-Cam, on the Subaru telescope at Mauna Kea
Observatories. We also discuss a future plan to promote a new deep survey with
this filter system (the MAHOROBA project).
