–Yamagishi Riko, January 2017
Yamagishi Riko (山岸理子) is a Japanese pop singer under Hello! Project as a member and leader of Tsubaki Factory. She first joined Hello! Project as a member of Hello Pro Kenshuusei in June 2012 and was introduced at the June 2012 recital alongside Nomura Minami.
Yamagishi Riko was born on November 24, 1998 in Chiba, Japan.
She was a part of DSK Dancer's Club prior joining Hello Pro Kenshuusei.
In June 2012, Yamagishi joined Hello Pro Kenshuusei after auditioning for the program. She was officially introduced as a member on June 17 at the June 2012 recital alongside Nomura Minami. Later that summer, she participated in the Morning Musume 11ki Member "Suppin Utahime" Audition alongside several other members of Hello Pro Kenshuusei, but failed.
Begining in 2013, Yamagishi began to take part in activites outside of Hello Pro Kenshuusei starting with the Winter 2013 Hello! Project concert tour, where she was a back-dancer for several performances. She then continued participating in every Hello! Project concert tour, as well as Soto Fest and the annual Hinatsuri Festival and Countdown Lives, as a trainee, until mid-2015.
After the conclusion of the winter Hello!Con, she participated in the stage play Nettai Danshi, which ran from February 7th to February 17, 2013, alongside Kaga Kaede. On March 6th, she participated in a fanclub event for newcomers Ichioka Reina and Makino Maria.
Starting on April 2013, Yamagishi was starring on the Hello Pro Kenshuusei original webshow Hello Pro Kenshuusei no Tadaima Kenshuuchuu!. The show concluded in September. Soon after, on October 5 a new webshow titled ~Onedari Entame!~ Hapi★Pure began airing. Hapi★Pure concluded on September 27, 2014, one year after it began airing.
In fall 2013, Yamagishi participated in Morning Musume's fall 2013 tour alongside several other trainees as a back-dancer. She was later chosen to be part of the opening and challenge act for Morning Musume's fall 2014 Budokan concert, S/mileage's summer 2014 Budokan concert, Berryz Koubou's fall 2014 Budokan Concert, and ℃-ute's spring 2014 concert tour,  ℃-ute no Hi concert at Nippon Budokan and spring 2015 concert tour alongside other selected trainees.
In late 2013, Yamagishi auditioned for a role with Engeki Joshibu and passed. She starred in the Engeki Joshibu musical Bokutachi Karen na Shounen Gasshoudan, which ran from March 14 to March 23, 2014, which also features Yasuda Kei, Ogawa Makoto and several other trainees. At around the end of the year, she participated in the stage play Kurukuru to Shi to Shitto, starring Niigaki Risa and Kikkawa Yuu. The stage play ran from December 3rd to December 11, 2014.
In 2015, Yamagishi was featured in the music video for ℃-ute's 27th single "Tsugi no Kado wo Magare," released on April 1st, alondside Kaga Kaede, Ichioka Reina and Horie Kizuki as back-dancers.
On April 29, 2015, it was announced that Yamagishi would be debuting in a new unit named Tsubaki Factory alongside Kishimoto Yumeno, Niinuma Kisora, Asakura Kiki, Ogata Risa and Tanimoto Ami. Yamagishi's response regarding the new unit:
That I entered the Kenshuusei and then am going to debut in such short fashion makes me nervous, but when I was chosen, I was also surprised. To think that all of those that have supported me until now will be with me forever makes me happy. In Hello! Project there are a lot of groups with varied personalities, I want us to become a group that can reliably put out our personality for everyone to see.
Yamagishi had her first performance as a member of Tsubaki Factory on May 4, during the Hello Pro Kenshuusei Happyoukai 2015 ~Haru no Koukai Jitsuryoku Shindan Test~ event.
On May 16, 2015, Tsubaki Factory's official blog was announced and Yamagishi made her first post.

Yamagishi was a second year middle school when she initially joined Hello Pro Kenshuusei in June 2012. When she joined Tsubaki Factory in April 2015, she was in her second year of high school. She graduated from high school in March 2017.

|Most airhead in Hello Pro Kenshuusei|
(March 2014 Issue of Gekkan Entame)
- She wanted to join Hello Pro Kenshuusei because she liked Minimoni when she was little.
- She thinks she won't lose to any other member in the droopiness of her eyes.
- She wants to be someone who makes everyone energetic and to be able to dance cool and sing.
- For her, the hardest thing about being a Hello Pro Kenshuusei is when she isn't chosen for things and when she feels like she hasn't improved at all.
- When asked what group she'd like to join, she answered Morning Musume. When asked again later, she said that her dream was to join a Hello Pro Kenshuusei unit.
- She wants to try singing "Crazy Kanzen na Otona" by ℃-ute.
- She sang "Kono Machi" for the Hello Pro Kenshuusei Happyoukai 2013 ~Haru no Koukai Jitsuryoku Shindan Test~ event and her number for the event was 15.
- She says that everything has gotten easier since she joined the program. She's progressed in singing and dancing and has gotten people below her. She thinks she's probably competent when it comes to rhythm but not so much with pitch. Still, she finds the lessons fun and is glad she joined the program.
- As of August 2015, she has the most theater work from the Kenshuusei.
- Fukumura Mizuki and Uemura Akari said that they are curious about Riko.
- Ever since she got her member color, she started to collect green colored items.
