↑Obon (mid-August) brings the city's most culturally charged week: ancestral memorial observances, Bon Odori street dancing in neighbourhood squares, and lantern-floating ceremonies at temples
↑Rain eases from July's tsuyu peak: 102mm is heavy by any normal standard but noticeably drier than June-July, and sunshine hours are at their summer best at 7.1 daily
↑Osaka's summer festival circuit is in full swing: neighbourhood matsuri, outdoor beer gardens, and the summer stall culture that makes Dotonbori even more theatrical than usual

↓The hottest month of the year at 34°C highs — genuine heat stress risk for those unacclimatised; schedule everything outdoor before 11am and after 5pm
↓Domestic school holidays push hotel prices to moderate-expensive and fill Universal Studios Japan, Kaiyukan Aquarium, and Osaka Castle to capacity
↓Obon week (August 13–16) means many small family-run restaurants and traditional shops close for the holiday period
