Osaka has four real seasons: a warm coat for December to February (highs around 10°C), light clothes for very hot, humid summers (34°C in August), and layers for spring and autumn.
Osaka is a city you walk, and day trips to Kyoto and Nara add even more steps. Comfortable walking shoes that slip off easily for temples and ryokan are the most important thing you'll pack.
June is the rainy season, and September can bring typhoons. Expect a lot of walking, especially on day trips to Kyoto and Nara. Japan uses Type A plugs at 100 V: two-pin Canadian plugs fit, but three-prong plugs need an adapter.
