Over the past few years I've been sporadically amassing a collection of information, largely in Japanese, relating to Honda Toru. Here I will try and collect everything I have thus far for the sake of those who might have been as curious as me. Links are slowly being added so please wait warmly.
The few archived podcast episodes, various PDFs of his books, archived webpages of interviews etc. (most in Japanese)
Notable inclusions: Denpa Otoko, Sekai no Denpa Otoko, Moeru Otoko and Nounai Ren'ai no Susume.
Honda-san's website on the Internet Archive.
(Onwards to 2D!) An internet radioshow hosted by Anime-kai (another popular otaku talkshow group) and Honda-san. Mostly discussing their current work, funny asides about their life and otaku culture. See my curated archive for all the mp3's I managed to unearth.
A good starting point for learning about Honda Toru. Mainly a brief overview of his ideals.
One of the few filmed interviews with Honda, and the rest of the video is quite good as well. This mainly concerns his ideas about No'nai romance and his core philosophies regarding love capitalism.
Excellent interview and a great overview for everything about Honda-san. The perfect starting place.
An interview about Honda-san's views regarding 2D, 2.5D and alternative relationships in Moe Manifesto.
本田透インタビュー 真実の愛を求め、俺たちは二次元に旅立った！ (Honda toru Interview - To seek true love, we must travel to 2D!)
2010 interview about Honda's light novel(s).
Season 2 episdoe 2 of BBC's "Japanorama" TV special, this episode is about otaku.
"内ゲバなんてやめろ！ 敵は外にいる、戦え！" (Quit the infighting! The enemy is outside, fight!)
An article about Honda-san's involvement with the TV drama of his light novel, 『ライトノベルの楽しい書き方』 (Light Novel no Tanoshi Kakikata)
My personal commentary and as comprehensive as I was able to manage at the time given limited resources.
I have no idea why this exists but it was cool find ww
