  The James Webb Space Telescope Time-Domain Field (JWST-TDF) is an $\sim$14$'$
diameter field near the North Ecliptic Pole that will be targeted by one of the
JWST Guaranteed Time Observations programs. Here, we describe our James Clerk
Maxwell Telescope SCUBA-2 850 $\mu$m imaging of the JWST-TDF and present the
submillimeter source catalog and properties. We also present a catalog of radio
sources from Karl J. Jansky Very Large Array 3 GHz observations of the field.
These observations were obtained to aid JWST's study of the dust-obscured
galaxies that contribute significantly to the cosmic star formation at high
redshifts. Our deep 850 $\mu$m map covers the JWST TDF at a noise level of
$\sigma_{850}$ = 1.0 mJy beam$^{-1}$, detecting 83/31 sources in the
main/supplementary signal-to-noise ratio (S/N $>$ 4 / S/N = 3.5 - 4) sample
respectively. The 3 GHz observations cover a 24$'$ diameter field with a 1
$\sigma$ noise of 1$\mu$Jy beam$^{-1}$ at a 0$.\!\!^{\prime\prime}$7 FWHM. We
identified eighty-five 3 GHz counterparts to sixty-six 850 $\mu$m sources and
then matched these with multiwavelength data from the optical to the
mid-infrared wave bands. We performed spectral energy distribution fitting for
61 submillimeter galaxies (SMGs) matched with optical/near-infrared data, and
found that SMGs at S/N $>$ 4 have a median value of $z_{phot} = $2.22 $\pm$
0.12, star formation rates of 300 $\pm$ 40 M$_{\odot}\,{\rm yr^{-1}}$ (Chabrier
initial mass function), and typical cold dust masses of 5.9 $\pm$ 0.7 $ \times$
10$^{8} $M$_{\odot}$, in line with bright SMGs from other surveys. The large
cold dust masses indicate correspondingly large cool gas masses, which we
suggest are a key factor necessary to drive the high star formation rates seen
in this population
