↑Tenjin Matsuri (July 24–25) is one of Japan's three greatest festivals: portable shrine processions, 3,000 people in traditional costume, a boat procession on the Okawa River with fireworks over the city — unmissable if your timing aligns
↑Summer in Osaka unlocks the city's rooftop bar culture and outdoor dining terraces — the heat and humidity are offset by cold Asahi draft beer and yakitori smoke on warm evenings
↑Fireworks festivals (hanabi) at various venues around Osaka throughout July are genuine spectacles, free to watch, and very Japanese in the best sense

↓Hot and humid: 33°C highs with 76% humidity make extended outdoor sightseeing genuinely taxing; plan outdoor activities for early morning and return to air conditioning by midday
↓Tenjin Matsuri weekend (July 25) brings the biggest crowds of summer — Nakanoshima and Tenmabashi station area become extremely congested
↓Rainy season (tsuyu) typically overlaps with early July: 185mm of rain means heavy downpours are regular, even as the festival calendar heats up
