Oiwa lost her parents at a very young age. That's when she started seeing lingering spirits.
She had an one sided love to Terada Tatsugorou, this caused a rivalry between her and Otose but she loses to Otose.
Later she met her husband Tagosaku and would later create a hot springs bath deep within the mountains to try and give the lingering spirits a place of comfort and rest before they went to the afterlife. Whether she was happy or sad, the spirits would always be there for her, and when humans couldn't be at her side, the spirits would be there for her instead. She wanted to give them a paradise, to at least allow them to enjoy a hot spring before passing on, and so she created the Senboukyou. She originally ran it with her husband, and an orphan named Rei, but now only runs it with Rei who has become a lingering spirit.
She soon had many souls coming to the Senboukyou before reaching heaven, and just to see them smile before passing on gave her a sense of satisfaction. However, after her husband passed away, she realized she had been alone all along, and started forcing the spirits to stay at her inn, instead of sending them to the afterlife, so that she wouldn't have to worry about being alone anymore.

Gintoki and Shinpachi saw a spirit behind her and desired to go back to Edo. Oiwa looked like she didn't know anything about the lingering spirits. However, it later turned out that she knew all about them, and also knew how to control them using peanuts, and use them as a means to battle with.
