Click on the above link and you will find a report of this visit. It is in Japanese, but the pictures will also tell the story. Maybe one of the Japanese readers might be able to give as a translation in due time.
These shows were (partly) recorded by fans in the audience. If there were any radio-broadcasts were planned, is not known to me. Info about these will be shared soon.
