Step into a tropical rainforest under glass domes, heated with hot water from the waste incineration plant next door. Yumenoshima Tropical Greenhouse Dome in Koto Ward grows more than 1,000 species of tropical plants, and next door the free Daigo Fukuryu Maru Exhibition Hall shows the real fishing boat caught in a 1954 hydrogen bomb test. Together they make a quiet, inexpensive half day near Shin-Kiba.
