Sadly its a 3 week trip with warm, cold, and professional complnents - so need to check a bag given the amount of variety I need, and I did plan to leave it with them. Still, I'll have a carry on to deal with somehow containing my clothes for the night, electronics etc.

I'm a little confused about opening hours. It seems some of th eurban parks have closing times listed, generally around sunset, which puts them out of my range. It also appears that SensoJi may be lit up nicely. Is it possible to see it at night, even if I cant go inside? That, plus some good dinner, might make a NEX roundtrip worth it. I do see that the train back to Narita at night may be a challenge as NEX stops running a bit early, but other lines are possible later.

Do folks think I could pull off a visit to the Narita san temple in the morning before an 1130 flight?
