Miraikan means ‘hall of the future’, and hands-on exhibits here present the science and technology that will (possibly!) shape the years to come. Don't miss the demonstrations of humanoid robot ASIMO (11am, 1pm, 2pm and 4pm) and the lifelike android Otonaroid (11.30am Monday and Wednesday to Friday, 11.30am and 2.30pm Saturday and Sunday). The Gaia dome theatre/planetarium (adult/child ¥300/100) has an English audio option and is popular; book online one week in advance. A multilingual smartphone app makes a game out of visiting.
