Kaji-san’s publication of 『Itsuka Subete ga Kimi no Chikara ni Naru』benefited me a lot not only as a voice actor, but also as another human being! It goes without saying for the people interested in this industry, but it would be great for even people who are not to read it too! I’ve been motivated greatly!

Kaji-kun’s book, 『Itsuka Subete ga Kimi no Chikara ni Naru』was really good. On top of his views of life and his views as a voice actor, it was very interesting to read about the differences between live-action actors and voice actors. Speaking of which, in the bookshop I (Ishiguro) went to, for some odd reasons this book was placed in the Foreign Literature (海外文学) section, could this perhaps be foreign literature…? (^^;;

I became engrossed with it and read it all in one night at one go. Having finished reading it, my thoughts are “I’m somehow really excited.” Meeting the various Kaji-sans in his teens, his twenties, and his thirties, all of which galvanized me, has given me encouragement. Now I too, am proud to be in this profession!! It was an awesome book!!!

Kaji-sannnn 😊

Itsuka Subete ga Kimi no Chikara ni Naru

It was a fascinating feeling as if I was peeking into Kaji-san’s secrets. I wish that I read this when I was 14, but even if I arrive at Kaji-san’s age now, I’d still want to read it many more times!!

Kaji-kun’s book that’s currently on sale
“Itsuka Subete ga Kimi no Chikara ni Naru”
It’s a book packed with Kaji-kun’s thoughts.
After reading this, I believe you’ll come to like him even more, and come to want to continue supporting him.
There’s also his story with Yonaga in there (*´꒳`*)
By all means, please get your hands on a copy and read it.
Recommend it too 💕💕

I received a copy of “Itsuka Subete ga Kimi no Chikara ni Naru” from Kaji-san. He told his story very honestly without hiding anything, rather than just voice actors, anyone who wants to receive a push on their back, I hope you would read it. And in order for this book to be even more widespread, I want to invite Kaji-san to many other programs!

( *˙0˙ )Oooooh
It appears that Kaji-kun published a book!!
As a person who’s known him back from
his lead-role debut in “Over Drive,”
it’s somewhat embarrassing… (//ω//)ゞ
The moment I received the book,
I was so happy and shocked,
so much that I burst out laughing LOL
He’s amazing!! (…)

We’re comrades-in-arms.

I’ve finished reading the book I received from Kaji-kun “Itsuka Subete ga Kimi no Chikara ni Naru”♪  Since it was written as part of the “Worldly Wisdom for 14 years old” series, it was packed with words directed to people at that age.

That said, it still contains hints for people of any age, any industry (…)

My senior whom I’ve always been under the care of, Kaji Yuki-san, had released a book titled “Itsuka Subete ga Kimi no Chikara ni Naru!”
It goes without saying for students who are unsettled about their future career, but even for myself who’s a working adult, the content moved my heart tremendously 🌸 By all means, please do check it out~!

(…) The book written by Kaji-kun, “Itsuka Subete ga Kimi no Chikara ni Naru” is really a good book. He’s straightforward, sincere, hates to lose, and I’d even say, awkward…… That kind of man’s way of life, is written right there (…)

During the recording session for Nanatsu no Taizai, I was told “If Tatsuhisa-san is willing to read it, I’ll happily give it to you.” And that’s how I got my hands on this book.

That guy is generally nice. Too nice to boot. Yet at times, he can be stubborn and difficult (…)
