Wrap up warm. It's freezing in Japan right now. Put on some more clothes. I'm sat bundled up in a Uniqlo Heattech crew neck t-shirt, a green long-sleeved turtleneck, a denim jacket and khaki chinos. My cousin is bundled up in two Heattech V-neck t-shirts, a punk shirt, sky blue chinos, a down coat, a scarf and gloves. Wear lots of layers in case the temperature goes down still further. The temperature has dropped fairly quickly over the last several days. Wrap up warmly. Be sure to keep warm and have enough rest. Bundle up!
