The shed as it appears in 1.0.
The shed as it appears in 5.2 and with the Ao Oni bursting out from the ground.
The shed (小屋 koya) is absent in Version 3.0 and Version 6.23 . It only appears in Version 1.1 and Version 5.2. In Version 6.23, The Old Building was made to replace the Shed since it is no longer used. Not much information can be given about the Shed due to its very low use. It can be seen more as a decoration.
Version 1.1[]
The shed is accessible once the player takes control of Kazuya, which is near the ending. He heads into The Shed and takes a rope ladder. He then proceeds to place it on the well and safely climb down, which switches the player's control back to Hiroshi.
Version 5.2[]
The shed can be used after recruiting your friends into the party, finding the oni eating the rope ladder, taking the shed key and jumping out of a window in the first floor of the Annex. Once entering the shed, the oni pops up from the floor and gives the player an endless chase. The shed cannot be found if you choose to escape alone, because if you escape alone, you won't be able to take the shed key and you will succesfully escape using the ladder.
