Walking around Kameido
Kameido is a neighborhood in east Tokyo (JR Sobu line from Akihabara to Chiba) which is not very touristy but it’s worth to take a stroll around its alleys. Nowadays the eastern part of Tokyo is the youngest and most lively part of the city (Shibuya, Shinjuku, Harajuku, etc), however during the Edo era the areas west and south of the Imperial Palace were the busiest ones.
Even though Kameido, in east Tokyo, was destroyed during the Second World War it still maintains certain aura of past times. Kameido is very popular for its gyoza and horumon ホルモン restaurants.
