Recommendations for special experiences?

We are travelling to Japan in October visiting Tokyo, Osaka, Sapporo, Sendai and Yokohama. We will be doing a day trip to Kyoto too whilst there and Kobe for some beef. We have been before to Japan hence not staying in Kyoto or some other places.

I have just found out I will be receiving a bonus from work to be paid in time for the holiday. I would be interested to hear of any unique and special experiences others have done so I could look into surprising my other half. Nothing off the table (though nothing with helicopters as I’m scared of those…!)
