In Hakone Kowakien Yunessun, a mountainous hot spring resort just a day trip from Tokyo, a spa park is offering a bathtub, shaped like a beer mug, filled with heated amber water and white foam with the aroma of hops and barley.

• 距离东京仅有一天路程的神奈川县箱根町是一个多山的温泉胜地。这里的一家温泉公园设了一种啤酒杯状的浴缸，浴缸内盛满了散发着啤酒花和大麦清香的热啤酒。
