There are a large number of options available, and while you can also visit Mt Fuji independently, a tour provides a great option to check out the area without having to work out the multitude of bus and train options for yourself. There are day trip options which include the Hakone Region and Lake Kawaguchi in the Five Lakes region.
Mt Fuji is located 137 km / 85 miles to the west of Tokyo, and can be seen in the distance on clear days. As Mt Fuji has a perfect circular volcanic cone it can be viewed from all directions, however for day tours from Tokyo there are two main areas on the eastern side of the mountain which are typically visited, Hakone and Lake Kawaguchi in the Five Lakes Area. Both areas can provide spectacular views of Mt Fuji. Hakone is situated to the south eastern side of Mt Fuji and is approximately 15-20km or 10-12 miles from the mountain. Lake Kawaguchi in the Five Lakes area is situated approximately 15km or 10 miles to the north of Mt Fuji, with Lake Kawaguchi being the main area visited by tours from Tokyo. Lake Kawaguchi is also a short distance to the Mt Fuji 5th Station, which is the starting point for visitors wanting to climb to the top of Mt Fuji.
A key point is that the roads between Tokyo and Mt Fuji can get very busy with traffic, particularly in peak times, so factor that into your expectations when planning your day tour. If a tour offers the option to return by Shinkansen then that can often be a faster method to return to Tokyo at the end of the day.
Best Time to See Mt Fuji?
Note that Mt Fuji is often covered by cloud which may limit viewing opportunities. When planning your visit to Mt Fuji monitor the weather forecast, and in particular the cloud factor. If the clouds are forecast to be more than 30% the chances of seeing Mt Fuji are less likely, although even on a cloudy day you can have breaks in the weather!
Mt Fuji 5th Station
Mt Fuji 5th Station is on Mt Fuji itself and is the starting point for people to climb Mt Fuji. You can also see views of Mt Fuji at that location. Note that the 5th Station is at an altitude of 2305m or 7560 ft, so ensure you take warmer clothes. There are periods where access to the 5th Station is not available, so tour companies will typically substitute an alternative activity.
