I love the way they’ve illustrated their graphics! Not just the iceman with 冬(“fuyu”, winter) written on his kabuto helmet, or the pink girl with 春 (“haru”, spring) in her hair, but the examples of how cold it is. They’ve chosen to illustrate the degrees of cold by what kind of drink freezes at each temperature. So, 水 (water) freezes in the pipes at about -5 degrees, ビール (beer) freezes at -10, and お酒 (sake) freezes at -15. Good to know!
