The evidence provided consists of general web search results and Wikipedia pages that do not contain specific details regarding a 60-year-old traditional dancer in Japan finding love with a protege 34 years her junior after two decades of being single. The web results are either irrelevant (e.g., general life advice, different age gaps) or do not mention the specific scenario described in the claim. Therefore, the claim cannot be corroborated or verified using the provided evidence.

The web search results confirm the existence and history of the Japanese television show 'Shinkon-san Irasshai!' (Welcome, Newlyweds!), noting it is a long-running show. However, none of the provided evidence confirms that a specific couple appeared in April and kept their identities private. The evidence only establishes the show's existence and general format.

The evidence confirms that 'Taishū engeki' is a form of traditional Japanese theatre and that troupes travel. However, none of the provided evidence mentions a specific individual who is a seasoned performer from Ibaraki, nor does it mention teaching at a specific troupe named 'Tsubaki'. The information is too specific to be verified.

The evidence provided contains general web search results and Wikipedia entries about unrelated topics (e.g., hot springs, manga, tanks). None of the provided evidence contains any information regarding a troupe named 'Tsubaki' being established by a woman's mother 40 years ago, nor any details about it having 50 members or touring hot spring towns. The claim cannot be verified or corroborated.
