Title: Future prospects of the cosmic noon
        -- mapping and resolving galaxy formation at its peak epoch --

Our Mahalo-Subaru project has been mapping out star forming activities
at 0.4<z<3.3 covering the peak epoch of galaxy formation, and across
various environments.  It employs a unique set of narrow-band filters
on MOIRCS/Subaru to search for Ha emitters associated to the
proto-clusters or in narrow redshift slices in the general field. We
have shown not only filamentary/clumpy structures of all the
proto-clusters but also a very rapid rise in star formation activities
with the lookback time.  We also show that the mode of star formation
in dense environment is more burst-like and dusty compared to that in
the field, due probably to galaxy-galaxy interactions.  HST images
from the CANDELS survey have revealed that nearly half of the Ha
emitters in the field at z~2 have clumpy structures, and among them
"red dusty clumps" are preferentially found near or at the mass center
of galaxies.  They are probably linked to bulge formation and
therefore this process is expected to depend on environment.

I will also present prospects from other on-going/future major
programs using a wide range of facilities from optical to (sub)mm to
increase samples and investigate in more detail the physics and mode
of star formation.
