In Hakone, the stay is part of the plan
Hakone is often about the accommodation itself: ryokan, onsen, dinner, a slower evening and possible Fuji atmosphere. Choose the area based on what you want the night to do for the trip.
Choose easier logistics for a first visit
If Hakone is only one night, simplicity usually beats maximum seclusion. Easier arrival and departure give you more energy for the experience.
Choose seclusion when the stay is the point
If ryokan and onsen are the premium moment, a more secluded stay can be worth it. But plan the day around the stay, not maximum sightseeing.
Fuji, onsen or loop route?
Do not optimize everything at once. Choose whether Fuji atmosphere, onsen time or sightseeing variety matters most.
When to get personal help
Personal planning is useful if Hakone is an expensive stay decision or has to fit between Tokyo, Kyoto and luggage forwarding.
