Does "Evening Get" correspond to a real-life television show? In chapter 2 of Orange, Hagita tells his friends that he has go home to watch Evening Get. The text outside the speech bubbles explains it as:


  Evening Get! It's a Nagano TV show that starts at 4:30. Ryuta Mine's gonna be on today's show.


Ryuta Mine appears to be a real Japanese actor from Nagano prefecture. Similarly, in ch.5*, Naho and Kakeru's friends give excuses for why they cannot walk home together with Naho and Kakeru. Hagita's excuse that he is going to watch Evening Get. Outside the speak bubble is:


  They're doing a story on Mino Monta's son &hellip;


Mino Monta also appears to be a real-life personality in Japan.

With these two instances in mind, does Evening Get correspond to a real-life television show? I have tried a bunch of internet searches but have no found anything of use so far. Perhaps someone who can read the original Japanese text might have more luck?
Yes, ゆうがたGet! (Yuugata Get!, Evening Get!) is a real-life TV show.
It's broadcasted by TV. Shinshu  located in Nagano prefecture since April 5, 1999. Based on the broadcast schedule list on the Wikipedia, the show started at 4:30 on the weekdays in:

April 1999 - September 2000 under the name of 「陽司★美恵子 ゆうがたGet!」, and
March 2010 - March 2014 under the name of 「情報ワイド ゆうがたGet!」


As already mentioned on the question, Ryuta Mine is also a real-life person. Based on the list of appearance on the Wikipedia, he appeared once every month on Wednesday in:

「情報ワイド ゆうがたGet!」, and
「ゆうがたGet!」

which means the story took place in between 2010-2014 instead of 1999-2000.

Regarding the episode of Mino Monta's son, I couldn't find the specific date/episode. but it's probably regarding

the arrest on 13 September [2013] of his 31-year-old son, Yuto Minorikawa (御法川 雄斗), who was charged with stealing a man's bag on the street in Tokyo.

Considering the publication month of chapter 5, the episode (if it existed) should be broadcasted before August 2012.

P.S. it might be possible that the author took the events that had occurred recently at that time since the manga was serialized in 2012-2015.
