Da Vinci Web and WalkerPlus have both released special interviews related to TK's Yureru (Shake) book.
They are two different interviews not the same one. Each asked TK different questions. Worth reading to get a deeper look into TK's writing process and his baby penguin mind.

WalkerPlus: Ling tosite sigure TK talks, "I felt that making this book was similar to the music I make."
These two special interviews are in Japanese but you should not have issues reading them if you use Google translate. Enjoy!
