It's not clear exactly when the castle was founded but it was likely in the 1440's. Early records claim that Ogasawara Nagatomo, Kiyomune's son, was born in the Hayashi Palace in 1443. Hayashiohjo Castle was the main castle of the Ogasawara clan until they were defeated by Takeda Shingen. The Ogasawara gave up in a nearly bloodless battle when they were surrounded by the Takeda forces in 1550. The castle was destroyed and abandoned.
Hayahshiohjo Castle is on a mountain ridge on the edge of the plain that stretches across modern day Matsumoto City and up the Yamabe valley extending east from Matsumoto. It has commanding views of the valley and the plain so it is easy to see why it was chosen for the Ogasawara's home castle. Hayashiohjo Castle combined with Hayashikojo Castle across the small valley to the south are often call Hayashi Castle together.
There is actually a road from the northeast side up to the top of the castle, but if you're going to walk it anyway, you might as well walk the main trail up the ridge. It's much more interesting. In particular, the main route up the ridge has countless small baileys all the way up.
