Tomokazu Seki works on versatility rather than volume, and the catalogue keeps proving that the quieter choice was the correct one.
The essay
Our editors on the work, the patterns and the reason this body of work holds together.
Tomokazu Seki appears in 42 films in the Nutevio catalogue, and none of them would work the same way without Tomokazu. Ultraman Regulos: First Mission is the clearest case: a film rated 10.0 by our editors, where the performance carries weight the script only implies.
The recognisable elements are versatility, transformation, screen presence. Watch two of these films back to back and the method separates from the material — the same instrument, tuned differently for fantasy, adventure, family. It is a style built on what is withheld as much as what is played.
Working with Tetsuo Yajima, Shojiro Nakazawa, Koichi Sakamoto and others, Tomokazu Seki helped set a standard other performers now audition against. Awards bodies have been slower than the work, which is usually the sign of a career built on choices rather than campaigns.

The defining work
#1
Ultraman Great (voice)
Ultraman Regulos: First Mission (2022)
Performance score9.9
The performance the rest of the career is read through. Ultraman Great (voice) gives Tomokazu Seki a structure to work against, and the film hands over its centre of gravity without hesitation.
View movie#2
Ultraman Ace
Ultra Galaxy Fight: The Destined Crossroad (2021)
Performance score9.5
Ultra Galaxy Fight: The Destined Crossroad asks for something the previous films did not, and gets it. Ultraman Ace is played without a single line of pleading for the audience's sympathy — which is exactly why it lands.
View movie#3
Ultraman Great / Alien Empera
Ultra Galaxy Fight: The Absolute Conspiracy (2021)
Performance score9.5
Ultra Galaxy Fight: The Absolute Conspiracy asks for something the previous films did not, and gets it. Ultraman Great / Alien Empera is played without a single line of pleading for the audience's sympathy — which is exactly why it lands.

Ryusoul Changer, Ryusoul Ken (voice)

Kishiryu Sentai Ryusoulger Special Chapter: Memory of Soulmates asks for something the previous films did not, and gets it. Ryusoul Changer, Ryusoul Ken (voice) is played without a single line of pleading for the audience's sympathy — which is exactly why it lands.

A guided path through the work, ordered so each film explains the next.
Best entry point
as Ultraman Great (voice)
Start here. Ultraman Regulos: First Mission is the clearest statement of what Tomokazu Seki does — accessible, 25 minutes, and rated 10.0 by our editors. No context required.
Our editors order this path by accessibility first and chronology second. You meet Tomokazu at the most legible performance, then move forward in time so each film reads as a response to the one before it rather than a repetition of it.
Kishiryu Sentai Ryusoulger VS Lupinranger VS Patranger (2020)
Keeps the action register of Ultraman Regulos: First Mission but asks for a colder reading of it.
Ultra Galaxy Fight: The Destined Crossroad (2021)
A deliberate change of key after Kishiryu Sentai Ryusoulger VS Lupinranger VS Patranger — same instrument, unfamiliar tuning, and the reason range gets mentioned.
Ultra Galaxy Fight: The Absolute Conspiracy (2021)
Same director as Ultra Galaxy Fight: The Destined Crossroad, different problem to solve. Watching them in order shows how much of the effect was the collaboration.
Kishiryu Sentai Ryusoulger Special Chapter: Memory of Soulmates (2021)
Same director as Ultra Galaxy Fight: The Absolute Conspiracy, different problem to solve. Watching them in order shows how much of the effect was the collaboration.

Follow the thread outward — director, film, co-star, and the film after that.
Categories of our own
Six editorial categories we apply to every performer we cover.
Most rewatchable
Ultra Galaxy Fight: The Destined Crossroad
as Ultraman Ace
The one that survives a fourth viewing. Nothing in the performance depends on surprise, which is why it keeps paying out.
Most emotional performance
Stand by Me Doraemon 2
as Suneo (voice)
Grief played at conversational volume. The film never asks the audience to cry; the performance simply makes it difficult not to.
Most influential performance
Ultra Galaxy Fight: The Destined Crossroad
as Ultraman Ace
You can hear this reading in other actors' auditions a decade later — the surest measure of influence there is.
Best ensemble performance
One Piece Film Red
as Rob Lucci (voice)
Work that makes everyone else in the frame better without ever pulling the camera towards itself.
Career defining performance
Ultraman Regulos: First Mission
as Ultraman Great (voice)
If the career had to be argued in a single scene, our editors would pick one from this film and rest the case.
In their films' words
“You can build a whole film around a performer who knows when not to speak. Tomokazu Seki has known it for a long time.”
Head to head
Put two careers on the same scale and see where the argument actually sits.
Ours alone
Recognitions handed out by this desk, on criteria no awards body uses.
Modern Classic Performer
Awarded
Defining performances delivered inside the last twenty-five years, in films already being taught rather than merely remembered.
Action Legend
Awarded
30 catalogue titles in action, each one a reference point for the films that followed.
Our desk
Best ending, best opening, best twist and the rest — categories we apply to everyone we cover.
Best ending
Kishiryu Sentai Ryusoulger Special Chapter: Memory of Soulmates
as Ryusoul Changer, Ryusoul Ken (voice)
The last five minutes reorganise everything before them, and hold up when you already know what's coming.
Best opening
Ultra Galaxy Fight: The Absolute Conspiracy
as Ultraman Great / Alien Empera
A first sequence that states the rules of the film without explaining a single one of them.
Most emotional
Doraemon the Movie: New Nobita and the Castle of the Undersea Devil
as Suneo (voice)
The film where the technique steps aside and lets the feeling arrive undefended.
Best twist
Psycho-Pass: Providence
as Shinya Kogami (voice)
A reversal earned by information the film gave you and trusted you to misread.
Best visual achievement
Ultraman Regulos: First Mission
as Ultraman Great (voice)
Images that would survive with the sound switched off.
Best action sequence
Ohsama Sentai King-Ohger vs. Kyoryuger
as Gerojim (voice)
Geography, stakes and consequence held in the same frame — spectacle you can follow.
Best dialogue
Stand by Me Doraemon 2
as Suneo (voice)
Lines written to be spoken, staged so the pauses do half the work.
Most underrated film
Bakuryū Sentai Abarenjā 20th: Yurusa Rezaru Abare
as Abarengecko (Voice)
The public vote sits below ours on this one, and the direction is the reason for the gap.
