Zeniarai Benten Shrine in Kamakura (now officially named Ugafuku-jinja Shrine) is a typical example of this phenomenon as it is believed that washing money in the spring within the cave in the shrine precinct will cause many times the amount to come to the bearer.
鎌倉の銭洗弁天（現在は正式には宇賀福神社）はその典型的な例で、同神社境内奥の洞窟内の湧き水で持参した銭を洗うと、数倍になって返ってくるという信仰がある。
