Those pages are up on the wiki - SM042 and SM043.

The thing on the site says, translated, "On the airings of September 14th and 21st, who Satoshi used to be together with in his travel, Takeshi and Kasumi, will be appearing two weeks in a row! What sort of great activities are the duo in for, and it's impossible to miss this!!" (9月14日（木）と21日（木）の放送に、かつてサトシと一緒に旅をしていたタケシと カスミが2週つづけて登場！ふたりがどんな活躍をするのか、絶対に見逃すな！！)

And by the way, the title for SM042 does not say Alola exists in Kanto, it's saying "Alola to Kanto" as in the greeting "Alola!!".
