1 to is equal to twice (reads as 'bai' in Japanese) 5 sho (reads as 'go sho' in Japanese), so Japanese people sometimes use this and do a wordplay how to read '1 to, 2 sho, and 5 go,' and the answer is 'goshobai masu masu hanjo' (means 'your business becomes more and more prosperous').
また、1斗が5升の倍にあたることから、「一斗二升五合」と書き「五升倍升升半升」と解して「御商売益々繁盛」と洒落として読むこともある。
