Masugatayama Castle was most likely built as an extended fortification from Karakai Castle, but it is not known during what time period specifically.
Masugatayama Castle is best visited along with Karakai Castle. In that case you'll want to follow the trails to Karakai Castle first and then back down through Masugatayama Castle. You could do the reverse, but I think it is more interesting and logical to start with Karakai Castle. However, be VERY careful of the trails as you walk from Karakai Castle. Just after the tower for electric power lines the main hiking trail continues off to the left and on to another mountain. What you need to do is to take the (much less travelled) trail to the right and up to the top of a small ridge or mountaintop called Monomiyama. from here you just follow the ridge down to the castle ruins and back down the mountain.There are no signs on this trail until the main bailey of Masugatayama Castle so be careful.
It looks like they have recently, probably this year, cut out a lot of trees around the main bailey of Masugatayama Castle and improved the trail going up from the bottom. I don't know what the purpose is but it would be great if they put up a few signs and continued to improve the trail going back through to Karakai Castle as well.
