Inside the walkway of the train station. Because It is hard for me to get an aerial view shot of the busy steeets.

If you have an iPhone, it’s easy. Open Apple maps, type in the location you want to go to (the crossing) and it’ll give you step-by-step directions how to get there (including easy to follow subway directions)

I stayed at the Shibuya Hotel En - literally just a few minutes walk and you’re there. Great hotel, excellent staff

It’s the center of Shibuya, so there’s everything to do here. I mean, the scrabble itself is a pedestrian crossing, but the Tokyu Food Show is underneath it, the Shibuya yokocho (along with hundreds of other restaurants) is maybe 300 meters away, there’s a virtual reality place around the corner. Yoyogi Park is within walking distance, you can see a show at the Tokyo Orb theatre at the top of the Hikarie building, you can visit the D47 museum which has a different exhibit every month or so... there’s an insane amount to do in this area.

Not sure about restaurants but there is a big Starbucks on one corner. The window seats were very busy but I think you’d have a decent view.

Hi, Take the Yamanote Line (JR Rail) to Shibuya one stop from Harajuku.

long enough

yes plenty of time, Tokyo is nowhere near as hectic as perceived. yes there are lots of people but it's all very civilised & calm.

Peak hour when offices open at about 9am
