Souya Monogatari is anime made by Ashi productions and Toei animation. It follows the journey of the Souya boat as it travels through Japans first expedition to Antarctica. Most of the character interaction may be fictional but overall follows the story of the characters aboard the ship. It's is kinda of like the anime A Place Farther Than The Universe but with no moe elements. The character design is pretty standard for the time and over all looks pretty basic. There is quite a few animation errors but overall they don't hinder the animes story. The water and ships do look quite good though. The OPis pretty catchy and works pretty well with the anime. The overall sound track though is just pretty good nothing really of note though.

There really not much to say about this if you want to watch anime about a expedition to Antarctica I would suggest A Place Farther Than the Universe Over this.
