<p>According to <a href="http://kabaneri.com/special/rokon/" rel="noreferrer">this post</a> on the official website, this is the 浄化マーク, meaning "purification mark". It is derived from / inspired by <a href="https://en.wiktionary.org/wiki/%E5%85%AD#Glyph_origin" rel="noreferrer">older variants of the character 六</a>, which is the "Rok-" in the phrase "Rokkon Shōjō" and means "six". This symbol is written on things to indicate that the things in question are "pure" (free of <em>kabane</em>, presumably). </p>

<p>I don't recall this being mentioned in the anime.</p>

<p>While watching <em>Kabaneri of the Iron Fortress</em>, I saw this symbol during the opening song:</p>

<p><a href="https://i.sstatic.net/4eIuo.jpg" rel="noreferrer"><img src="https://i.sstatic.net/4eIuo.jpg" alt="symbol painted on the Iron Fortress"></a></p>

<p>But what exactly does this symbol stand for? Is it ever mentioned what this stands for? Have I missed something? I also think I saw it once in the first episode, painted on the train, so I'm guessing it is the symbol for the train itself, but I'm not sure... I just want to know for what is this symbol used. </p>

While watching *Kabaneri of the Iron Fortress*, I saw this symbol during the opening song:

[![symbol painted on the Iron Fortress](https://i.sstatic.net/4eIuo.jpg)](https://i.sstatic.net/4eIuo.jpg)

But what exactly does this symbol stand for? Is it ever mentioned what this stands for? Have I missed something? I also think I saw it once in the first episode, painted on the train, so I'm guessing it is the symbol for the train itself, but I'm not sure... I just want to know for what is this symbol used.

According to [this post](http://kabaneri.com/special/rokon/) on the official website, this is the 浄化マーク, meaning "purification mark". It is derived from / inspired by [older variants of the character 六](https://en.wiktionary.org/wiki/%E5%85%AD#Glyph_origin), which is the "Rok-" in the phrase "Rokkon Shōjō" and means "six". This symbol is written on things to indicate that the things in question are "pure" (free of *kabane*, presumably).

I don't recall this being mentioned in the anime.
