but recently I talked with an member of the JMSDF and he told me about an "Emergency Chocolate Bar" inside of every inflatable life raft in a ship for the Jmsdf, with similar characteristics to the US D ration bars. so im wondering if anyone has any infomation on this "emergency chocolate bar" or any other type of emergency rations used by the JMSDF or JASDF. 
Any info would help, thanks
