Staying Warm at Outdoor Hanami
Assuming "cherry blossom season means it's warm" is the top cause of getting chilled.
The temperature swing in late March and April is bigger than you'd think
During peak bloom, roughly late March to early April, it's common for daytime highs to reach around 15°C while mornings and evenings drop to near 5°C. Dress light because the afternoon feels warm, and you'll feel the chill hit hard the moment the sun starts going down. Picnic-style hanami, where you sit on the ground for hours, makes it worse - cold rising from the ground lowers how warm you actually feel.
Why a light rain jacket doubles as a great windbreaker
Spring weather changes fast, and a sudden light rain shower is common. A lightweight rain jacket works as more than rain gear - it blocks wind and functions as a warm layer too. It also packs down small, which matters when you're trying to keep your hanami load light.
For everything else, check the cherry blossom viewing packing list - it adapts to your style and the time of day.
Heat packs are essential for a long night session
If you're planning a long night of yozakura, bring plenty of disposable heat packs. Warming your core (back, stomach) and extremities (feet) is the most effective combination. If you'll be sitting on the ground for a while, a blanket over your lap helps a lot too.
Layering that's easy to add or remove is the golden rule for clothing. Start with a thin base layer for the warm afternoon, then add jackets as the temperature drops.

Frequently asked questions
How big is the temperature swing during hanami season?
Daytime highs near 15°C can drop to around 5°C in the morning and evening. A warm layer is essential.
Can a rain jacket substitute for a warm layer?
Yes. A windproof, lightweight rain jacket covers both rain protection and warmth, and cuts down on gear.

Your back, stomach and feet - warming your core and extremities together is considered most effective.
Any other tips for sitting on the ground?
Use a blanket over your lap to cut down on the cold rising from the ground.
How should I choose my clothing?
Layer up with pieces that are easy to add or remove - a thin base layer plus jackets you can add as needed.
