"Power for the purpose of facing evil that passive bystanders pretend not to notice. That is the creed of Kawahiru Dojang. And you both, as our disciples, are meant to be products of this principle. If that is the case, then we, as the Masters, can not back down now and allow the forces of darkness to do as they please. The enemy generals are moving out... something's going to happen. Therefore, we must also make our move!"

- Seireitou speaking to Minato Kuramoto and Hinata Kūsūhana as he, Saori, and Jihan move out to handle the Ikken Kyūkage.

Kawahiru Dojang (河の昼道場, literally "place of the surrounding daytime's way") is a martial arts institution located in the Kabuki District of Rukongai. It is run by Seireitou Kawahiru and Saori Sumeragi. Minato Kuramoto and Hinata Kūsūhana are the only two students whom receive tutorship and also reside here.

Nishishō
There are two Masters that reside in Kawahiru Dojang, nicknamed the Nishishō (二師匠, "Two Masters"); namely, Seireitou Kawahiru and Saori Sumeragi. In addition, following the nineteen-month timeskip, there is Jihan Kanda that is normally associated with the Dojang, due to often being used to train the Dojang's disciples, such as Minato. Each of the Masters have incredible powers, and all bear signature titles that distinguish their capabilities and experiences. They are powerful enough that L'Obscurité acknowledged them as a militaristic threat, right beside that of the Gotei 13 and the Royal Guard, despite being severely few in number.

Despite being immeasurably powerful, it is a commonly shared trait among the Masters of Kawahiru Dojang that they are all very odd and eccentric. They are all prone to immature behavior and have trouble interacting with normal people due to the fact that they unconsciously release massive amounts of spiritual pressure. That is, to say, that given specific circumstances, they are more than capable of concealing their presence. Such is seen when Seireitou demonstrate battle strategies to Minato on separate occasions, in which he states one thing, but demonstrates exactly the opposite, still achieving the same result regardless (ie. Seireitou said not to face a larger enemy head on but was able to hold him off with brute strength by using his toes to grapple onto the lid of a manhole directly beneath him). However, an ongoing gag at the Dojang is that whenever there are disagreements between the Masters, they immediately get fired up and argue with each other as each one believes it will quickly resort to blows. However, it never resorts to this, and instead somehow leads to heated debates between the five in who is the strongest warrior by boasting about their respective fighting achievements in the past. Regardless, the five (including the Dojang's two residential students, Minato and Hinata) are very close, to the point that Seireitou considered them a family.

Minato remained Seireitou's student, but often receives lessons from the other two Masters. A recurring gag among the masters at the Dojang is that whenever they become spirited or motivated, their eyes seem to glow and emit light.
