Wirecutter editor Tim Barribeau waxed poetic about Hasami porcelain in 2017 and again in spring 2020, and in his stead, I will do the same. My favorite mugs—like Tim’s—are from Hasami, a Japanese ceramics company. I bet one of these mugs, given the chance, will become your dad’s favorite, too. Hasami mugs are gorgeous porcelain pieces that always look like a set, no matter what size or color you end up buying. They’re easily (and pleasantly) stackable, making it a joy to view more than one on your shelves. To start, I recommend investing in the 13-ounce mug in gloss gray, which is, in my opinion, the perfect size in the most striking color available.
