The story begins thirty years after the rapid and almost entirely peaceful Meiji Restoration which saw Japan undergo sudden and rapid modernisation, having up until that point, been a relatively isolated land ruled by a Shogan and local samurai on behalf of the Emperor. In a very short passage of time Japan managed to transition into what was for the most part, a recognisably modern, westernised state. Japan had been so successful, in fact, that in 1902 Japan and the United Kingdom of Great Britain and Ireland signed the Anglo-Japanese alliance. The alliance was renewed several times lasting until 1921. During that time the UK worked closely with Japan, in particular there was considerable cooperation between the two countries’ respective navies.
A major part of Japan’s modernisation effort was to build up its military forces, primarily to prevent colonisation by the world’s major colonial powers, including Britain, France, America and particularly Russia, against whom Japan fought a decisive war prior to its alliance with Britain. In building up these forces Japan needed to recruit lots of young men.
One major problem the Japanese military experienced though, was with recruits suffering from the disease Beriberi, which causes a variety of debilitating neurological disorders. A British trained Japanese naval doctor called Takaki Kanehiro was able to determine that the cause was a deficiency of vitamin B1 due to a diet of almost nothing but highly polished white rice the recruits tended to eat. The government needed to ensure recruits were receiving adequate vitamin B1 and the cheapest, most easily available source was wheat grain. However Japanese sailors from poor rural areas didn’t want to eat bread which they regarded as snack food or have cereals added to rice which was too reminiscent of food regarded to be the staple diet of rural peasant farmers they were familiar with back home. What the authorities needed was a way to disguise the presence of wheat in the rice.
At around the same time, Japanese naval officers were enjoying numerous liaison dinners with their British counterparts as the two navies improved relations and exchanged tactics and technological knowhow to strengthen their new alliance. One of the foods served aboard ship was a type of curry, a curry that the British had long ago adopted from India, which for more than a century had been a major British colony, and while most cultural flow resulted from the forced implementation of British education and administration systems, the British had conversely been the recipients of a number of Indian customs including elements of Indian cuisine, prime among which, was a taste for curry.
It wasn’t long before Japanese officers realised curry could be the answer they had been looking for and a variation on the British recipe was mixed with wheat and ultimately served with rice to the men. The men soon developed a taste for Curry Rice and when they eventually returned home they retained their affection for the dish which eventually spread throughout Japan leading to its popularity today.
