The Boso Peninsula (房総半島, Bōsō Hantō) is the large peninsula just east of Tokyo across Tokyo Bay. With its mountainous interior and many beaches along its shoreline, the area comes with a resort-feel and is also popular for its flowers which start blooming as early as February.
No more than 15 kilometers away from Tokyo at its closest point, the Boso Peninsula is well connected to the city by train, bus and expressway. The fairly developed western coast faces Tokyo Bay and is connected to Tokyo via the Aqua Line expressway, a combination of tunnel and bridge. The more rural southern tip offers natural and historic sights and scenic views as far as Mount Fuji on clear days, while the eastern coast faces the Pacific Ocean and has beaches popular among surfers.
