Scenic spot of Yamanaka Onsen: A hand-made cup with the motif of Tsurusenkei. The inside is a healing yellow-green gradation, and the outside is green with the addition of the red of the umbrella on the riverbed. You can feel "wabi-sabi" with contrasting colors inside and outside. You can put soup or other soup in it and drink it by holding the handle, so you can use it without touching the cup even if you put hot food in it. It can also be used as a bowl or as a dessert with ice cream. Dishwasher and microwave oven-safe plastic substrates are sprayed painted one by one by craftsmen, and when the lid is opened, vivid colors spread.
