Staying warm in Japan

Japan’s answer to staying cosy when you are out and about are these handy heat packs, called Kairo.

Kairo are a single-use heat pack that stay hot for between 8-14 hours depending on the brand You pop them into your pocket to keep your hands warm or attach them to your clothing such as an undershirt or my favourite the inside of my winter coat. They are surprisingly effective. There are Kairo especially designed for the feet and neck and the eye ones pictured are a great way to relax at the end of the day.
