In the "The Kano Chronicles® – Kano Shihan in fact and fiction Part I"
Blog article by Lance Gatting (Dec. 2019), he discusses the lack of evidence for subsequent stories of the victories by Kōdōkan Jūdō (講道館 柔道) over the older Jūjutsu (柔術) schools in Meiji era (明治) matches (see below).

However, that notwithstanding, it should be noted that Kōdōkan Jūdō Champion Yokoyama Sakujirō (横山 作次郎) does provide a first hand account of the drawn match between himself and Ryōi Shintō-ryū Jūjutsuka Nakamura Hansuke (中村 半助).

"An anonymous scholar acquaintance spent hours looking for evidence of the famous ‘police jujutsu competitions’ and told me he came up empty-handed, which in turn spurred me to look, too. Neither of us uncovered any contemporaneous articles in newspapers of the day, which we thought very strange; such activities by the police were normally very carefully covered by the press. Only 20-30 years later do the tales appear of the great police jujutsu tournament in which the Kodokan judoka were victorious and were hired as police jujutsu its allies, but only from Kano shihan and his supporters.. While it is entirely possible there was such an event, it seems more likely that if it did exist, it was a relatively small affair. Certainly some Kodokan judoka were hired as Tokyo Metropolitan Police jujutsu instructors around that time, but so were instructors from a number of other, different jujutsu schools; the public records of this are clear. The entire affair may be a combination of some (ahem…..) exaggeration on the part of Kanō shihan and his hagiographers and most definitely misunderstanding of the complex relationship of the Tokyo Metropolitan Police with martial arts, particularly kenjutsu (sword) and jujutsu (grappling)."
