Born in 1994-11-30 (?) & is 157cm tall. Or migth be born in 1994-04-08 or 1997-03-21, we have now found three different birthdays for her, which one is it? Who knows 
Probably one of the 1994 one's is correct.
She has released AV works mainly under the name of Megumi Takanashi (高梨めぐみ) & nude idol movies with the name of Nonoka Umeda (梅田ののか).
Set includes movies:
2014-07-25 - KAWD-547 - 初撮りkawaii 素人娘Vol.3 19歳の処女喪失 - めぐみ
2014-08-25 - KAWD-564 - 教えて美鈴先生! ホップステップAV女優♪ - 高梨めぐみ & 川菜美鈴
2014-09-25 - KAWD-574 - 処女喪失から3ヵ月で初めてイッちゃった!
2014-10-22 - YRH-064 - 完全ガチ交渉！噂の、素人激カワ看板娘を狙え！ vol.17 - <- I tried to cut only Megumi's parts from this movie but for some reason it also deleted the audio completely (I tried couple of times) so I also kept the whole movie, so there's the full one and Megumi's part only, with no audio.
2015-01-23 - PROU-027 - 解禁美少女 <- Nude idol movie
2015-03-20 - SHL-034 - 美少女即ハメ白書 34 - 高梨めぐみ, 逢沢るる, 陽木かれん & 原波瑠 - <- again I tried to cut her parts only but for some reason the cutting system had some problem with the file and didn't want to do it. Normally I only encounter this with all MKV-files.
2015-04-09 - DVDES-830 - 顔出し！女子大生限定 マジックミラー号 素人娘初めての電マ体験3 乗車人数10人達成！イった数は合計124回を漏れなく収録でまさかの2枚組6時間スペシャル！！in池袋～パンティの染みができてもオマ○コ汁の糸が引いても悶絶イキ我慢！～ <- this name was so ridiculously long that the torrent system won't approve it's usage so I shortened it.
I also shared this movie before:
2014-11-28 - MMR-AA002 - 初♥恋ノート
And in there I promised to make a set torrent for her works that I have found, you can find that torrent from here:

She also has released at least one full AV movie that I don't have, I added the cover pics of these missing ones to the torrent:
2014-10-10 - SIRO-2041 - 素人AV体験撮影774 - めぐみ 19歳 学生
At least one nude idol movie:
2015-03-27 - MBR-AA006 - 梅田ののか セキララヌード
And has appeared in at least two compilation movies, I don't know if there's any new scenes in those:
2015-10-19 - RBB-065 - 高画質 発射寸前！我慢汁垂れ流しの気持ちいいフェラチオ320連射16時間 第4弾
2016-01-19 - RBB-078 - 発射寸前！2人以上からご奉仕されるハーレムフェラチオ16時間
