Below. the obituary translated in full:
The writer, Noboru Yamaguchi has fallen to the battle against his sickness at the young age of 41 years old on April 4th, 2013. Yamaguchi first made his name in writing for video games, then made his professional novelist debut through the Kadokawa Sneaker Bunko label in the year 2000.
In 2004, his "Zero No Tsukaima" novel was first published by the MF Bunko J label and it quickly became a hit, fascinating many fans and resulting in 20 volumes and 5 spin-off novels while contributing to 4 seasons worth of anime. MF Bunko J and Media Factory feel sincerely indebted to Yamaguchi Noboru sensei and his "Zero No Tsukaima" series. He was indeed, our benefactor.
Just like his work, Yamaguchi sensei had a bright and cheerful personality and was loved by many of his friends, editors and anyone who had met him. He was always comfortable in his own skin and full of courage and humor, which have not changed from the first time I have met him to the very end, even during the hardships that he endured mentally and physically.

Yamaguchi had confirmed in 2011 that he had advanced-stage cancer that was originally considered inoperable. However, during an unrelated gallstone surgery, the cancerous growth was confirmed to have shrunk in size. Yamaguchi then learned that there was surgery that he could have that might cure the cancer. He reported later that year that this surgery ended without incident, although he returned to the hospital at the end of 2011.
