Tendon
The clue is in the name, a portmanteau of ‘tempura’ and ‘donburi’. Tendon is therefore a bowl of white rice topped with deep-fried seafood and vegetables. Today, tempura has evolved into a cuisine in its own right, with some specialist restaurants charging tens of thousands of yen for an elaborate set menu, yet tendon remains a humble, affordable dish loved by the masses. Made with fresh seafood that's fried in sesame oil (usually) until golden and crispy, tendon is a go-to fast-food when you need something filling and satisfying.
