I haven't been yet (it's also our next OS holiday!), but DH has been 4 times and worked there for a while teaching English. His sister also spent a year there on an exchange program and they've made really good friends with her host family and they come out here often to visit us.

Anyway, he loves it! He says it's incredibly safe in the city, they have Disney Land (which is a lot cheaper than going to the US one) and a few other big theme parks (similar to the ones we have in QLD) the country is absolutely beautiful, lots of cheap buys/bargains and everyone is friendly! My SIL went over for Yoko's wedding (our friend) and the photos were amazing (full traditional wedding - 7 dress changes!!).

The family friends are from ***uoka, and he spent a lot of time there before travelling and spending some time in Tokyo.

I have some links but not sure if I can post them here???

DH went to most of the theme parks, he went with just a few basic Japanese words but said it was really easy to pick up more (he's currently trying to teach me some before the family come out here in 7 weeks for the wedding!).

If you want more specifics, I can ask him when he gets home from work

Have fun planning, it will make for a wonderful holiday destination (from what he has told me about it anyway!).
