Just for info as to why I added "Toshiji Kobayashi" to the alternative names list and adjusted the English description, this page here explains that the reading of his name is actually "Toshiji" (same kanji, less common reading), so I've added it as an alternative name. Other interviews in Japanese also mention this.

The main name still needs to be "Nenji Kobayashi", since that's his stage name, this content issue is just for anyone wondering why I adjusted the English description.
