Spotted news online that the official website for the “Yama no Susume” anime adaptation of the “ヤマノススメ” slice-of-life manga by Shiro, announced that not only will a new OVA titled “Yama no Susume: Omoide Present” be released during the fall of 2017, but that a third season of the anime is set to air in 2018!

Now I have a reason to survive.
