You can make a short and simple transfer
between Tsukuba Express line and Toei Subway Oedo Line
in Shin-Okachimachi Station(s),
where the subway platform is just above the Tsukuba Express platform
and the ticket gates for the two lines are close to each other.
http://www.mir.co.jp/route_map/shin-okachimachi/yardmap.htmlTsukuba Express Asakusa Station (Exit/Entrance A1) is
just near your hotel [Richmond Hotel Premier Asakusa International].
http://www.mir.co.jp/route_map/asakusa/yardmap.htmlProbably the quickest (and also easiest) way is
to walk for a few minutes to this station,
go by Tsukuba Express line
on a train for Akihabara until the next Shin-Okachimachi Station,
make a transfer to Toei Subway,
proceed by Oedo Line
on a train for Ryogoku and Daimon to Tsukijishijo Station
and walk to Tsukiji Market.
