1. Overview of Tokyo’s Weather in May
May in Tokyo is considered one of the most pleasant months of the year, marking the transition from spring to early summer. The weather is typically mild and comfortable, with increasing sunshine and longer daylight hours. Rainfall begins to increase slightly toward the end of the month, signaling the approach of Japan’s rainy season in June, but overall, May is a relatively dry and sunny time for visitors.
Daytime temperatures usually range between 18°C and 25°C (64°F to 77°F), while nighttime temperatures are cooler, averaging around 15°C (59°F). Humidity levels are moderate, making outdoor activities quite enjoyable compared to the more humid months that follow. The clear skies and blooming greenery create an ideal backdrop for sightseeing, photography, and exploring Tokyo’s many outdoor attractions.
One of the most attractive aspects of visiting Tokyo in May is the abundance of seasonal flowers and gardens in full bloom. Parks such as Shinjuku Gyoen, Ueno Park, and the Imperial Palace East Gardens are especially beautiful during this time. Additionally, major sightseeing spots like Asakusa, Shibuya, and Tokyo Skytree are less crowded than in the peak tourist seasons of April and summer.
Visitors will find that May offers a balance between favorable weather and manageable crowds. Since Golden Week—a major holiday period in Japan—usually occurs in the first week of May, travelers planning to visit during that time should expect busier transportation and higher accommodation costs. Outside of Golden Week, however, hotels and attractions are generally less congested and slightly more affordable, with average hotel prices ranging from ¥10,000 to ¥18,000 per night (approximately $70 to $125 USD).
In summary, Tokyo’s weather in May is ideal for travelers who enjoy outdoor activities, scenic walks, and a relaxed sightseeing pace. Light layers, comfortable footwear, and an umbrella for unexpected showers are generally all that is needed to enjoy the city during this beautiful season.

Tokyo in May experiences mild and gradually warming weather as the city transitions from spring into early summer. The average daytime temperature hovers around 22°C (72°F), while the mornings and evenings remain cool, with average lows around 15°C (59°F). It is not uncommon for some warmer days to reach up to 27°C (81°F), particularly toward the end of the month. These temperatures make May one of the most comfortable months for outdoor exploration in Tokyo.
Humidity in May begins to increase compared to the drier months of March and April, with average relative humidity levels ranging from 60% to 70%. While still comfortable for most travelers, the rising humidity is a sign of the approaching rainy season, which typically starts in early June. Precipitation in May averages around 130 mm, with about 10 to 12 rainy days throughout the month. However, rain usually comes in short showers, and full-day rainfall is relatively uncommon.
Wind speeds in Tokyo during May are moderate, offering a refreshing breeze in the city’s many open areas and parks. UV levels also increase this time of year, so it’s recommended to use sunscreen and wear hats or sunglasses when spending extended periods outdoors.
Weather variability in May is relatively low, but travelers should still prepare for occasional fluctuations in temperature and sudden light showers. Layered clothing, such as a light jacket or cardigan over a t-shirt or blouse, is ideal for adjusting to different times of the day.
For those concerned about budget, it’s worth noting that May (excluding Golden Week) offers reasonable prices for travel and accommodations. Hotel rates outside of peak periods generally fall between ¥10,000 and ¥18,000 per night (roughly $70 to $125 USD), making it a good time for cost-conscious travelers to enjoy Tokyo comfortably.
Overall, the average temperature and climate conditions in Tokyo during May provide a near-perfect balance of warmth, low rainfall, and manageable humidity—ideal for sightseeing, outdoor dining, and experiencing local festivals or garden strolls.
3. Recommended Clothing for Daytime and Nighttime
In May, Tokyo’s weather is generally mild and pleasant, making it easy to dress comfortably for sightseeing and daily activities. However, the temperature difference between day and night calls for thoughtful layering. During the day, average temperatures range from 20°C to 25°C (68°F to 77°F), while the evenings can cool down to around 15°C (59°F). Travelers should aim for flexible outfits that adapt to both warm afternoons and cooler mornings or nights.
Daytime Clothing: For the daytime, light and breathable clothing is ideal. Cotton shirts, short-sleeved blouses, and lightweight trousers or skirts work well. Dresses made from airy fabrics are also a great choice for staying cool while walking around. Sneakers or comfortable walking shoes are essential for exploring Tokyo’s extensive public transportation system and walking routes through neighborhoods like Harajuku, Shibuya, and Asakusa. Sunglasses and a wide-brimmed hat can help protect against UV rays, which become stronger in May.
Nighttime Clothing: Once the sun sets, temperatures tend to drop, especially in open or riverside areas such as Odaiba or near the Sumida River. A light cardigan, denim jacket, or thin windbreaker is recommended for nighttime outings. For those planning to dine at rooftop restaurants or explore Tokyo Tower or Roppongi Hills in the evening, having a warm outer layer can make the experience more comfortable. Layered outfits such as long-sleeved tops with removable outerwear work best to accommodate these changes.
Footwear and Accessories: Given the possibility of occasional rain, it’s a good idea to pack a compact umbrella and shoes that can handle slightly wet pavement. Waterproof sneakers or low-cut boots are practical choices. In addition, wearing socks with closed shoes helps keep feet warm during cooler evenings.
Budget Tip: If you find yourself unprepared for the weather, affordable fashion retailers like UNIQLO and GU are easily accessible throughout Tokyo. You can purchase a light jacket or sweater for around ¥2,000 to ¥4,000 (approximately $14 to $28 USD), making it easy to adapt your wardrobe without overspending.
Overall, dressing in light layers, choosing breathable fabrics, and carrying a light jacket ensures comfort and flexibility for the changing temperatures throughout the day in Tokyo during May.
4. Clothing Tips for Different Activities (Sightseeing, Dining, etc.)
May is an ideal month for a variety of outdoor and indoor activities in Tokyo, thanks to its comfortable climate. However, different activities may require slightly different clothing choices to ensure both comfort and appropriateness. From casual city strolls to fine dining experiences, thoughtful wardrobe planning will enhance your overall travel experience.
Sightseeing:
For daytime sightseeing, especially when visiting popular destinations like Asakusa, Meiji Shrine, or the gardens of the Imperial Palace, opt for breathable and comfortable clothing. Lightweight pants, skirts, and cotton shirts are excellent for walking long distances. Comfortable walking shoes or sneakers are a must, as Tokyo’s public transportation often involves a lot of walking and stair climbing. A backpack or crossbody bag will help carry essentials like a water bottle, sunscreen, and a foldable umbrella in case of sudden showers.
Shopping and Casual Outings:
When shopping in districts like Shibuya, Harajuku, or Ginza, stylish but comfortable outfits are recommended. Casual dresses, layered tops, and trendy but practical shoes are common among locals and blend in well with the fashionable atmosphere. A light scarf or cardigan can be handy when moving between outdoor and air-conditioned indoor spaces.
Dining Out:
Tokyo offers a wide range of dining experiences, from casual ramen shops to upscale kaiseki (traditional multi-course meals). For casual dining, smart-casual attire such as a clean shirt and neat pants or a simple dress is sufficient. For fine dining, especially in high-end areas like Marunouchi or Roppongi, a slightly more polished outfit—such as a blouse with slacks or a semi-formal dress—is recommended. Men may consider wearing a collared shirt and loafers. These outfits not only match the atmosphere but also reflect cultural respect.
Outdoor and Nature Activities:
If you plan to visit nature parks like Inokashira Park or go on a day trip to Mount Takao, functional clothing is key. Athletic wear, moisture-wicking fabrics, and hiking shoes are suitable for such excursions. A light windbreaker or jacket is useful, especially in higher elevations where temperatures may drop.
Cost Consideration:
If you need to adapt your clothing during your trip, affordable options are widely available. Retailers like UNIQLO, GU, and Muji offer stylish, seasonal clothing at reasonable prices. A basic outfit—such as a shirt and pants—can be purchased for about ¥4,000 to ¥6,000 (around $28 to $42 USD), making it easy to adjust to Tokyo’s weather and dress norms without breaking your budget.
By planning your outfits based on activity, you’ll stay comfortable, stylish, and ready for any adventure Tokyo offers in May.
