Mt. Takao is only 599 meters high, and it is the most climbed mountain in the world. About 3 million people go up it in a year, and the 2007 Japan edition of the Michelin Green Guide gave it three stars, alongside Mt. Fuji. What surprises business travelers most is that it sits about an hour from central Tokyo: a sacred mountain that can be reached on impulse.
Its value as curation is that a group enters a living faith without effort. Takaosan Yakuoin, said to have been founded by the monk Gyoki in 744, enshrines Izuna Gongen, whose attendants, the tengu, are believed to turn away misfortune and bring good fortune. On the way up the flank, the cedar approach, the gate and the tengu figures arrive in turn, and the walk becomes a light pilgrimage into mountain worship. A cable car and a chairlift serve the route, so guests of any fitness reach the ridge and its view of Mt. Fuji, which is what makes this the way to reset a team between long meeting days.
Mt. Takao is the first answer to "half a day outdoors, an hour from central Tokyo". Forest bathing, mountain worship and an open view of Mt. Fuji sit in the gap between dense meeting days, and because there is a cable car and a chair lift, differences in fitness are not a barrier. Note that a guide or a group itinerary has to be arranged separately: the official site offers no standing group product.
