Onsen are Japan's hot springs along with the bathhouses and traditional inns built around them. Japan has roughly 25,000 hot spring sources, and about 3,000 onsen establishments use their naturally heated water. Bathing traditionally happened outdoors in open-air baths called roten-buro, though many inns now also have indoor baths called uchiyu. Since most homes have their own bath, public bathhouses have declined, while hot spring resort towns called onsen-gai have grown since the Second World War. You can spot an onsen on signs and maps by the symbol ♨, the kanji 湯 meaning hot water, or the hiragana ゆ.

Hampi is a UNESCO World Heritage Site in Karnataka, India, with more than 1,600 surviving remains spread over 4,100 hectares. It was the capital of the Vijayanagara Empire from 1336 to 1565. Travellers from Persia and Portugal described it as a prosperous, wealthy and grand city with temples, markets and farms along the Tungabhadra River. By 1500 it was estimated to be the world's second-largest city after Beijing, and probably India's richest at the time. In 1565 a coalition of Muslim sultanates defeated the Vijayanagara Empire, its capital was conquered and destroyed, and the city was left in ruins. Hampi remains a religious centre, with the active Virupaksha Temple at its heart.
