Running from Shinjuku and Ikebukuro stations through Tokyo's western suburbs and all the way up to Kawagoe and Chichibu in Saitama, the Seibu train lines are great for exploring some of the city's less trendy 'hoods, filled with age-old public baths, run-down shopping arcades and quirky parks, not to mention rowdy izakayas, ethnic eateries and box-sized cafés.
Our complete guide to fun along the Seibu lines takes you from the heart of Tokyo all the way to the historic town of Kawagoe, which features one of the few remaining Edo-period streetscapes, and scenic Chichibu, where you can do things like spend a night in a temple and go river rafting in a traditional wooden boat. Check out our picks below and start exploring – and consider also reading up on 'Aranumano', one of the most interesting areas along the yellow train's tracks.
