After reaching Lake Okutama at the end of the Mukashi Michi trail, I spent some time on the Ogouchi Dam itself. I then walked in the area north-west of the dam: There are some nice view points of the lake. Finally, I ended the day by hiking up Mount Kurato (倉戸山). However, the view at the summit was blocked by trees so it was a bit of a letdown. I also managed to get lost on the way down… Another option would have been to walk the combined Ikoi trail (奥多摩湖いこいの路 ; literally “Lake Okutama Relax Trail”) + Lakeside Path (湖畔の小道), two easy trails that follow the south bank of the lake all the way from the dam to the so-called Drum Bridge (a floating bridge), near the Ogouchi Shrine.
