Below is a map of Asakusa with the major attractions numbered. Asakusa sits just outside the loop of the Yamanote Line one suburb over from Ueno. The Ginza line of the Tokyo Metro is probably the best bet to get to Asakusa if you get off at Asakusa Station you can check out the nearby Asahi beer headquarters, Senso-ji Temple and walk up to the kitchen district of Kappanbashi-Dori. You could then return via the Ginza line at Tawaramachi Station.
