Big busy, busy, busy city.
I couldn’t wait to get out of it and explore!
If you like temples & shrines Nikko & Kamakura are ace (daibutsu is BIG!) quite touristy (Japanese tourists) but not tacky.
Sod the guide, plan what you want to do and you’ll find people who will help you when you are lost 🙂 Loads of people speak English, but aren’t necessarily forthcoming.
Sumo is good fun if you are there at just the right time – turn up early for cheap seats, reserve by putting something on it and it’ll be waiting for you when you return for the big bouts.
Trying to find addresses e.g. for a recommended restaurant can be a nightmare, so allow plenty of time.
Getting to Fuji area wouldn’t take long by shinjuku, climbing it wouldn’t be high on my list, but (if you get a clear day – often cloud-shrouded) the views would be great.
Looks like it’s got some gnaarr rock gardens 🙂
