Kamogawa Seaworld Joyful Spring

Spring comes early out on the Boso Peninsula, and Chiba's Kamogawa Seaworld aquarium celebrates the season with a number of fun events taking place in March and early April. A special night-time killer whale show will take place at 5.30pm on Saturdays and Sundays (plus Fri Mar 27, Mon 30 & Tue 31), while overnight stays at the park (Mar 21, 27 & 28, Apr 4) can be booked now. Call 04 7093 4803 (Japanese only) for reservations – the rate is ¥12,000, including dinner and breakfast, and you need to bring a sleeping bag with you. Full details for all the spring events are available here.
