On March 16, the platforms for the Tokyu Toyoko Line at Shibuya Station moved from the chijō nikai (地上二階, second floor) to the chika gokai (地下五階, fifth basement floor) to connect the Toyoko Line with the Tokyo Metro Fukutoshin Line.

To make that change, the old Toyoko Line platforms closed on March 15.

The conversion of the train lines meant that for the two days of the transformation Shibuya became a magnet for tetsudō fan (鉄道ファン, train fans), along with tetsudō otaku (鉄道オタク, train geeks) or toritetsu (which can be rendered as either 撮り鉄, train-photo-taking geeks, or 録り鉄, train-recording geeks).
