The storied Odawara Castle, set within 3.5 miles from the Ichinoyu Shinkan as well as the western-style hillside botanical garden "Hakone Gora Park" placed just a 10-minute drive away are well worth visiting. If you are willing to explore even more landmarks in Hakone, attend the tranquil Soun-ji Temple located within a 17-minute stroll from the property.
