Wondering whether June is a good month for Tokyo? The short answer: early June is recommended, mid-June is not, and late June is conditional.

This guide pulls together Tokyo's June weather, rainy season timing, what to wear, and travel timing in one place — based on Japan Meteorological Agency normals (1991–2020) and the National Astronomical Observatory of Japan (NAOJ) 2026 official data.

What to Wear in Tokyo in June | Early, Mid, Late

Early June (1–10)

Average temperature around 22°C, with relatively little rain.

• Recommended combo: short sleeves + light cardigan or shirt
• Umbrella: one folding umbrella is essential
• Shoes: water-resistant sneakers
• Women: dress + thin cardigan / Men: short-sleeve shirt + cotton pants

Mid-June (11–20)

Average 23–24°C, 4–5 rainy days. This is the peak of the rainy season.

• Recommended fabrics: quick-drying polyester, linen
• Umbrella: a sturdy one (Tokyo gets windy, and small folding umbrellas can flip inside out)
• Shoes: water-resistant sneakers or sandals (avoid leather)
• Outerwear: light waterproof jacket or windbreaker
• Women: short dress + leggings / Men: short sleeves + cropped pants

Late June (21–30)

Average 24–25°C, average humidity 75%. The air feels noticeably heavier.

• Recommended: breathable clothing and sweat-wicking fabrics
• Shoes: breathable sneakers or sandals
• Bag: waterproof bag or vinyl cover
• Women: a cool dress + sun protection / Men: short sleeves + shorts

✅ If you get cold easily: thin long sleeves + cardigan (indoor air conditioning runs strong)

✅ If you run hot: short sleeves + quick-drying fabrics

✅ If you have allergies: mask + eye drops (watch out for mold allergies during the rainy season)

Tokyo June Travel Timing | When to Avoid the Rain

Best Times to Go

• June 1–10 (early month): rainfall is still light and hydrangeas are just starting to bloom. Top recommendation.
• Last week of June (26–30): the rainy season is winding down and the hydrangea season is at its final peak. Second-best pick.

Times to Avoid

• June 13–25 (peak rainy season): it rains almost every day and outdoor sights get tough. That said, if your itinerary leans indoors, this window can still work.

Recommended Timing by Travel Style

Japanese Public Holidays in June

June has no public holidays in Japan, so there's no Golden Week–style crush. That actually works in favor of weekday travelers.

Because it's the rainy season, mid-June flights are often the cheapest of the entire year. Early and late June run a bit higher than the deepest off-season but are still on the affordable side.

Tokyo June Rainy-Season Packing List

Clothes & Accessories

• Light jacket: one windbreaker or thin jacket
• T-shirts: 3–4 short-sleeve (you'll sweat)
• Pants: 2 pairs of quick-drying
• Socks: 5–6 pairs of sweat-wicking

Umbrella & Waterproofing

• Umbrella: a sturdy regular one beats a small folding one
• Bag: waterproof bag or vinyl cover
• Shoes: water-resistant or quick-drying
• Poncho: a lightweight portable one

Medication & Sun Protection

• Sunscreen: SPF 50+ (UV is still strong even during the rainy season)
• Cold medicine: immune systems take a hit during tsuyu
• Mosquito repellent: mosquitoes start appearing in late June
• Allergy medication: for rainy-season mold allergies

Tokyo June Travel Essentials

• eSIM: a slow-loading map on a rainy street corner is genuinely frustrating. A Japan eSIM with unlimited data is faster and cheaper than carrier roaming — set it up before you leave.
• Tokyo Subway 24h/48h/72h Pass: moving between indoor sights without getting drenched means using direct subway-station passages. An unlimited subway pass takes the cost pressure off and lets you cherry-pick indoor spots.
• Tokyo + hotel package: few things are worse than dragging a heavy suitcase across wet pavement. For a June trip, lock in a value hotel that's directly connected to a subway station or no more than 3 minutes on foot.
