With investment banks facing an uncertain future, one Nomura shareholder has come up with a novel suggestion to help to boost its share price: replace all office toilets with Japanese-style squat facilities. 

"All toilets within the company's offices shall be Japanese-style toilets, thereby toughening the legs and loins and hunkering down on a daily basis, aiming at achieving four-digit stock prices," the shareholder said on the bank's website ahead of this month's annual meeting on June 27.

"The company can surely avoid failure if they straddle over a Japanese-style toilet every day and strengthen their lower body. If it cannot, it can only be accepted as a bad luck."
