Japan should launch in the coming days an S-310 probe rocket from Kagoshima to conduct an "experiment to observe the two-phase flow behavior and heat transfer characteristics during the inertial flight of a rocket".
The launch was scheduled for January 9, but was postponed due to bad weather.

It will be the 56th flight of the rocket, which can be launched from Japan or Antarctica.

The launch is now scheduled for January 9 at 8:00 UTC from the Kagoshima (Uchinoura) Space Center. The rocket is already on the pad! (With a nice Mu-3S in the background...)

Interesting... Has it ever been launched from Antarctica?
Off-topic (mods please move to more appropriate thread if needed) what other rockets have been launched from Antarctica?

Yes, several times. The last time was in 1985 though.

Many French rockets took off from Antarctica (Véronique, Dragon and others), but also from the French island of Kerguelen a little north of Antarctica.
Japan has also launched some sounding rockets from this continent.
(In photo it's the launch of a French Dragon)

What other rockets have been launched from Antarctica?

The sun setting over Japan. Not sure yet if the launch was successful.

Fast and furious. Hopefully there will be another video perspective with less choppiness near 1st stage burnout.
