Seiyuu

Although many people would expect Nishiyama to be a prolific seiyuu when it comes to voicing characters in anime, truth is that he is a seiyuu with few credits, even fewer if we count leading roles.

Music

Koutaro Nishiyama has been one of the most active seiyuu when it comes to be in music projects.

As a singer, Nishiyama has come a long way.

He started off not confident as a singer, lacking control while having a high, nasal pitch that did not work well. He worked that around and has showed on multiple occasions that he can pull off singing that will impress you however, he still lacks the consistency to do so.

All these projects were and are a pivotal part in his growth as a singer and performer – some groups require him to not only sing, but also dance -, therefore watching his growth has been one of the most exciting things for his fans.

Facts

Inseparable from the 81 Produce gang

Oreiya 2017
Oreiya 2017

The Eguchi-Nishiyama-Saito trio is well known among seiyuu and seiyuu fans.

The dynamic 81 Produce trio has been, since their debuts, working together in a wide variety of projects that range from music to variety and showcase a chemistry like no other seiyuu group.

Eguchi is the “veteran” of the trio and was instrumental in showing the ropes of entertainment to Nishiyama, taking him under his wing in Oreiya and sponsoring him a spot for his own variety show in 2016, Sokuboku.

Saito is the same age and both trained at 81 Produce around the same time.

Since early on they have been part of various radio projects together. As time flew by, both started to meet in music projects or other variety shows. Saito always speaks fondly of Nishiyama despite mocking him frequently for his speaking quirks.

The trio has known each other for over 10 years and showcase one of the closest-knitted friendships in the seiyuu industry.

Easy-to-mimic voice

Not necessarily a novelty but Nishiyama’s voice has been countlessly mimicked by his peers.

Seiyuu from 81 Produce – Takuya Eguchi, Soma Saito, Tetsuya Kakihara (former 81 Produce), Yoshiki Nakajima – have a close to perfect technique, copying his tone and mannerisms leading to funny situations whenever it happens.

Close friends with Toshiki Masuda, Yuichiro Umehara and Yusuke Shirai

His friendship with Toshiki Masuda, Yuichiro Umehara and Yusuke Shirai started to be noticed by fans in the Binan Kouko‘s early days. The trio was part of the main cast and quickly hit it off when hosting the same variety show connected to the anime series.

Their chemistry instantly shows when they are together and any show that features him with any of the two will certainly have a lot of teasing and fun going on.

KINDAN SIRI PARTY FOR YOU 2020

Posing for photos can easily be “ruined” by Nishiyama’s “charisma”. When it comes to photos, he is not afraid of going a bit overboard with his poses and when on camera – whether for a live broadcast or a recording of a variety show – he often throws his image under the bus in favor of a funny moment on camera.

As a result he is known a one of the seiyuu meme kings, with plenty of funny moments of his captured on GIF.
