Wataru Date (伊達 航 Date Wataru) is a character in the manga and anime franchise Detective Conan.
Wataru Date was a former police officer from Tokyo Metropolitan Police District under the Criminal Investigation First Division. He was later assigned to be the mentor of Wataru Takagi, and together they became known as the "Wataru Brothers." He was dating an English teacher, Natalie Kuruma. Unfortunately, he got caught up in a car accident after one of his stake outs with Takagi and died one year ago. A year later after his death, it was discovered that Date was an acquaintance of Tooru Amuro, whom he had met while attending a police academy.
Date was considered to be a "carnivore"-type of a man compared to Takagi (by Miwako Sato) and could be described as an aggressive person. In addition to these, he was also a kind and caring person as attested by his interactions with Takagi and his text message to Amuro.
 Plot overview
 Relationships analysis
 Wataru Takagi
Date was Takagi's mentor and close friend. He passed away from a traffic accident. As the pronunciation of his name was the same as Wataru Takagi's, Date said they were "Wataru brothers" (ワタル・ブラザーズ).
 Tooru Amuro
Wataru Date and Tooru Amuro were friends in the police academy; Amuro was the top-ranked student, while Date held second place. While Date went on to become an officer, Amuro went somewhere else and fell out of contact with Date for unknown reasons. Date's last text to Amuro asked him where he was and chided Amuro to communicate once in a while. Amuro was shown visiting Date's grave, and likely left a toothpick out of respect for Date; Date used them habitually.
 Name origin
Wataru Date shares his first name with police sergeant Wataru Takagi, which prompted him to make a nickname for the both of them: "Wataru Brothers." However, the kanji that represented his first name was different to that of Takagi's. His name is written with the kanji 航, which has the ON-reading of kou (コウ ). Meanwhile, Takagi's is written with the kanji 渉, which has the ON-reading of shou (ショウ ). This similarity in first name became an important factor in the Overnight Deadline case. Date's last name played an important role in the said case as well.

Wataru Date died one year ago (File 804, Page 4), when Sato was only about 27 years old, which means that Date's estimated age at the time he died was 28.
