What to Wear

What to Wear in Tokyo in July

Tops

Short sleeves; sweat-wicking fabrics are best

Outerwear

A light layer for air-conditioned trains and buildings

Bottoms

Breathable pants or skirts, or shorts

Shoes

Sneakers or sandals; sneakers if you'll be walking a lot

Accessories

Hat, parasol, sunscreen, handheld fan and something to drink

When visiting temples and shrines, it's best to avoid very revealing clothing. Oku-Nikko and Karuizawa drop to around 15°C in the morning and evening, so bring a long-sleeved layer.

Good to Know

Watch out for heatstroke

After the rainy season, both temperature and humidity are high, and heatstroke cases rise. Drink water and replace salt often, and take breaks during the day. On days when the Ministry of the Environment issues a heatstroke alert, limit long outdoor activities.

Sightsee in the morning and evening

Stick to indoor sightseeing (museums, aquariums, shopping) during the day and save outdoor spots for mornings and evenings.

Sudden thunderstorms

Summer afternoons can bring sudden downpours and thunder. Keep checking the rain radar in weather apps.

Mt. Fuji climbing season

Mt. Fuji's trails open on July 1 on the Yamanashi side and July 10 on the Shizuoka side. Even in summer, the summit can drop below 10°C, so proper gear is essential.
