The beaches of the Boso Peninsula make for a popular and relatively easy daytrip or overnight journey from Tokyo. The eastern coast faces the open Pacific Ocean, making it one of Japan's premier surfing destinations. Meanwhile, the western coast offers calmer waters and views of Mount Fuji when visibility is very good.

Beach huts and rental shops are typically open only during the official swimming season which typically lasts from mid July through August. These places provide beachgoers with showers, changing rooms, shaded rest areas, food and drinks. Surfing is a popular activity all year around, and there are a number of surf shops especially along the Kujukurihama Coast. Lifeguards patrol the beaches during the summer.

Snorkeling is not a popular activity on the Boso Peninsula except around the islands of Okinoshima and Niemonjima where small fish can be seen. Clamming, on the other hand, is a popular activity from spring to early summer, especially along the Kujukurihama Coast.
