When in the year will you travel?
Crowdedness in Sanyo Shinkansen trains can depend on seasons.
Seats which cannot be reserved
in JR Shinkansen and Limited Express trains,
which are often called like "non-reserved seats",
are secured on a first-come, first-served basis;
in a crowded train car of non-reserved seats,
you may have to stand or sit on the floor.
frog1954:
Mizuho and Sakura departs at Shin-Osaka Yes;
Mizuho and Sakura trains go on the Sanyo and Kyushu Shinkansen,
and when they go west, they start from Shin-Osaka Station.
In Shin-Osaka Station,
Track 20, where many Sakura trains depart, is a little tricky;
this track is not accessible directly from the Shinkansen concourse;
between the concourse floor and the platform floor
is a mezzanine, where you can change elevators.

You can go up

then go further up to your Shinkansen platform.
