This is one of the hottest summers we've had in Japan. Why does it feel so hot?
One reason is that people are trying to save energy. There is less air
conditioning in buildings.
If you go outside, you should use some of the new products in stores.
You can buy cooling scarves and towels that you wear around your neck.
There is also cooling gell that you apply to your neck.
You also need salt. You can buy salt candy or eat "umeboshi."
