Sometimes in Japan (and the same can be said for life in general), I have absolutely no idea what is going on. Today, a red carpet has been placed in the middle of a busy road. Not only does this carpet obstruct many motorists who drive down here every day, but it actually stretches the entire length of Kappabashi Street – and Kappabashi Street is a very long street indeed. Is the head of state making a surprise visit? Is some type of awards ceremony about to take place, perhaps? Or is there no reason at all for this vermilion impediment? Only time can provide the answer.

For the last few months, I have been trying my hand at a little private English conversation practice with just one student—a 71-year-old Japanese man who has lived in Asakusa all his life. With a keen interest in food and Japanese history, he has provided me with an endless source of knowledge about post-war Japan and the changing attitudes amongst Japanese people. I enjoy teaching him, and our conversations often cover an array of topics, such as Bonseki, China Syndrome, and foods I’ve never heard of before in my life. Today, we are heading out to try such a food.

He drives us across Tokyo to Yotsuya. On the way, he starts a conversation with the dashboard of his Toyota, instantly reminding me of something from a science-fiction movie. In Yotsuya, we visit a shop called Ariakeya. The shop specialises in selling just one dish—a Japanese delight known as ‘tsukudani’.

If I were to ask anyone to name three foods associated with Japan, tsukudani probably wouldn’t even get a mention; and, if I’m completely honest, I had never heard of it until last week. Tsukudani most commonly involves seaweed, meat, or fish (often pond fish) that has been simmered in soy sauce and mirin. It can be eaten up to a year after it is made. Many years ago, this was a staple food in Japan, but due to its high salt content, it has become somewhat less popular, with concerns about salt being bad for health and such.

The woman in the shop is very pleasant and can speak excellent English; she has even prepared an English menu for me in anticipation of my arrival. I am offered samples of various dishes before settling on my favourite, Maguro—cubes of tuna. Soft, but surprisingly chewy at the same time, the outside is extremely salty but very sweet. The middle offers a dryness that you would expect from marinated cubes of cooked tuna. Overall, the fish is pleasantly moreish.

As we leave the shop, I notice a small tray of salt outside the entrance to a restaurant, guarded by a shisa—an Okinawan dragon. Curious about the purpose of this salt display, I ask my student. In his usual enthusiastic way, he explains to me that many years ago, the Emperor of China lived in a Palace so big that the only way he could get anywhere fast was to ride around on the back of a bull. Inside the Palace, the Emperor had three thousand women, each in separate rooms. Every night, the Emperor would tour the Palace on the back of his faithful bull and decide which woman he would spend the night with.

The women knew that the Emperor rode around on a male cow; I mean, everyone knew, it was hardly a secret. The women were all desperate to marry the Emperor, for the wealth and status they would receive if such a ceremony occurred. Finally being freed from their solitary rooms in the Palace was often considered a secondary incentive. Somehow, the women discovered that the bull liked eating salt, so every night, they would place saucers of salt outside their rooms. The bull would smell the salt, stop to eat, and hopefully, the Emperor would choose that room to spend the night. Somehow, this tradition of salt piles outside of rooms came over to Japan, and salt is now placed outside many restaurants. Bulls represent customers, or so the custom goes. The story made me wonder if the idiom ‘Like a bull in a china shop’ took any of its origin from the same story, but before I have time to ask, we are back in Asakusa, and I have a red carpet to inspect.

Back at Kappabashi Street, some women are singing in front of a man that I think is supposed to be a clown. Eventually, though, answers come, and the reason for the whole street being closed off becomes apparent.

A kappa (or at least a man dressed as one) follows the red carpet, walking the length of Kappabashi Street. The kappa stops intermittently to wave at the passing crowd, walking alongside an old woman carrying a scroll, and has a big red heart painted on its back. I have no idea why. No idea about any of this.

Back at home, I dine on my neatly wrapped packet of tuna cubes, which cost ¥432. Tsukudani is usually enjoyed with rice, but I will snack on this salty-sweet tuna as it is. Unfortunately, this type of food is not too pleasing on the eye; it might look like something you would serve to a domestic animal or a bull, but its taste suggests that this might be a bit of a waste. The tuna is, in fact, delicious and perhaps one of the best foods I have tried in months. The only problem, again, is the high salt content, but that shouldn’t put you off trying it at least once.

I seldom place links to other websites, but I genuinely enjoyed the food from Ariakeya, and they were very nice to me, so here is their shop:
