The names of the mountains surrounding 檜原村 in western Tokyo are varied. Examples include 三頭山, 練行峰, and 醍醐丸. Further afield, there are famous mountains like 八ヶ岳.

I have found some explanations for the differences between the suffixes 山, 岳, and 峰 in this site, but would like to understand the nuance for 丸 as an indication of 'mountain.'

The suffix 峰(みね、ほう) is supposedly for "peaks", 山(やま、さん) is supposedly for "mountains", but the actual usage is kind of mixed. I'm not sure if there is a good explanation beyond X is common and Y is uncommon. The distinction can be blurry partly because whether to call a geological feature an independent mountain or a peak that is part of a larger mountain is kind of arbitrary. (I'm sure scientists have a clear definition, but many names have been used for a long time since before the definition.)

suffix mountains peaks
-峰(みね、ほう) common common
-山(やま、さん、ざん) common rare
-岳(たけ、だけ) common common
-丸(まる) rare uncommon
