  In the first image of the James Webb Space Telescope (JWST) of SMACS
J0723.3-7327, one of the most outstanding features is the emergence of a large
number of red spiral galaxies, because such red spiral galaxies are only a few
percent in the number fraction among nearby spiral galaxies. While these
apparently red galaxies were already detected with the Spitzer Space Telescope
at $\sim3-4{\rm \mu m}$, the revolutionized view from JWST's unprecedented
spatial resolution has unveiled their hidden spiral morphology for the first
time. Within the red spiral galaxies, we focus on the three most highly red
galaxies that are very faint in the $<0.9\,{\rm \mu m}$ bands and show red
colors in the $2-4\,{\rm \mu m}$ bands. Our study finds that the three
extremely red spiral galaxies are likely to be in the Cosmic Noon (i.e., $1 < z
< 3$) and could be consistent with passive (i.e., $\sim$ zero star-formation
rates) galaxies having moderate dust reddening (i.e., $A_{\rm V}\sim1\,{\rm
mag}$). These "red spiral" galaxies would be interesting, potentially new
population of galaxies, as we start to see their detailed morphology using
JWST, for the first time. Finally, we note that the spectral energy
distribution of these red $z\sim2.5$ galaxies could mimic $z>10$ Lyman break
galaxies and contaminate to $z>10$ galaxy samples, especially when they were
faint and small.
