June is the best month of the summer season to travel to Osaka. The temperatures are comfortable and there is generally less rain compared to July and August. Additionally, there are fewer tourists and hotel prices are lower. Just be prepared for some occasional rainfall.
Fewer tourists: During this time, there are no Japanese holidays, particularly on weekdays, which leads to lower hotel prices. Additionally, rainy days mean that popular tourist attractions would be less crowded.
Osaka offers many indoor attractions that are unaffected by the weather. Apart from Universal Studios Japan and nearby Nara, you could explore indoor sites, such as shrines, temples, aquariums, and shopping districts, without worrying about the rain.
If you're traveling during this month, we recommend the following preparations.
Choose early to mid-June: Traveling in early to mid-June is preferable to late June as rainfall tends to increase and lasts longer later in the month.
Tips for visiting Universal Studios Japan: Be prepared for rain. Light rain usually has little impact and you wouldn't have to wait in long lines. However, if the rain intensifies, outdoor attractions may temporarily close and, during thunderstorms, more rides would be suspended until staff notify guests that they are operational again.
Tips for visiting Nara Park: If it rains, your interaction with the deer is typically unaffected. However, the paths could become very muddy, so it's important for both the elderly and children to be cautious. Be sure to wear waterproof and non-slip shoes while walking on the grass.
Flexible itinerary: Try to keep your schedule flexible, aiming to visit only 1–2 places per day. If you're unsure how to plan your itinerary, contact us to assist you.
