Culinary Backstreets guide Mairi Wallace explains the differences between three Tokyo food tours: historic Yanesen, creative Kichijoji and community-minded Monzen-Nakacho, and what each neighborhood reveals about the city.

Ramen may have seen a worldwide boom in recent years, but when it comes to soba – Japanese buckwheat noodles – fans might say they’ve been unfairly neglected. “Soba have a history of at least 400 years, as long as sushi. Yet they’re almost completely unknown abroad,” chef Yoshinobu Saito says, pondering the concept behind his first ever restaurant. “I guess I don’t have a specific concept for the store. But I do want to promote soba worldwide.”

Unusual takes on ramen abound in Tokyo, from carefully balanced chocolate and lamb creations for Valentine’s Day to algae-tinted blue broth, but few leave you with cravings and daydreams lasting for weeks. Adding a quality twist on ramen is a challenge – simplicity is one of the dish’s most vital elements, as with most Japanese cuisine. Yet friends Yamada and Sumida struck gold with one perfectly measured twist: smoke. Tucked away near Rikkyo University in a quiet area filled with student-friendly restaurants and cafés, their modest ramen joint Kemuri (which means “smoke” in Japanese) serves their latest experimental dishes without straying from the joy of good ramen at its best – quality ingredients cooked to perfection.
