I went to Japan in February this year and my trip included Tokyo, Osaka and Kyoto.

In Tokyo I stayed at Annex Katsutaro Ryokan and in Kyoto at Ryokan Shimizu Inn. I found them both great, I stayed in Japanese style rooms that had futon beds and western bathrooms (you're own, not shared). They were both about 10 000 yen per night for 2 people.

Places to see in Kyoto that I enjoyed were Kikakuji, Kyomizudera and Fushimi Inari shrine.

Himeji Castle is well worth the 1 hour train ride to get there. It may look the same as Osaka castle from the outside but it is all original on the inside where as Osaka castle has be re-built fairly recently and is a museum inside.

I stayed a bit out of Osaka in a traditional Ryokan called Guesthouse Yougendo. It is between Osaka and Nara (which is also a good place to visit). It's a great place to stay for a real Japanese expereince

All the places to stay I mentioned have websites so check them out if you're interested.
