What is the ruling on consuming Japanese products that contain alcohol and gelatin, such as biscuits that contain a percentage of alcohol, for a person residing in Japan who does not know their language?

One should be cautious about foods to which a percentage of intoxicants or pork has been added, due to the difficulty of reading the labels on them, as the Prophet, peace and blessings be upon him, said: "Leave that which makes you doubt for that which does not make you doubt."
