Otaku (おたく / オタク) is a Japanese term used to refer to people with obsessive interests, particularly anime, manga or video games.
The ultimate otaku room? Dakimakura, wall scrolls, retro gaming machines, custom figures, eroge, doujinshi, Dr Pepper, dedicated Tohou machine and more! This place looks more like a shop or museum! Posted by member Nanashi over at figure.fm.
A room like this is known as an Itabeya [痛部屋[いたべや]]. The kanji “痛” is now commonly used to refer to illustrations of cute 2D girlies being plastered over any type of object – a car for example is called Itasha [痛車[いたしゃ]].
