The story is the weakest aspect of Aa Harimanada, it doesn't have much of a story line. The plot revolves around Harimanada disregard for Sumo tradition which doesn't go down well with the Sumo sports authority(SSA). Rest of the anime revolves around the tussle between Harimanada and the authority.
The story is simplistic and there aren't any/many twist and turns in it. The good thing is there aren't any fillers .
For a 90's anime the art is okay. One gripe i had was that the faces of many of the antagonists looked similar and i couldn't tell the difference. Also some of the background scene were used repeatedly and in some instance you couldn't tell whether the crowd were upset or happy.
The background music in this anime was good and enhanced quality of different scenes in the anime. The voice acting was spot on and portrayed the characters pretty well.
The characters in the anime including main character were one dimensional. Neither the protagonist nor the antagonist motivation for what they did were fleshed out. While the anime did make a flimsy attempt at showing why the SSA was upset with Harimanada, but it felt contrived. Nor was any attempt made to explain why Harimanada had such disregard for Sumo traditions and why he started acting up after he became yokuzuna and not before.
While the story is weak and characters are one dimensional. Harimanada's rebellious nature and overwhelming strength will make you enjoy the show. Even though the story is predictable you will still want to know how Harimanada takes on the Sumo world from the get go.
The strongest aspect of the anime is it's fight scene's.There are lot of them and it is not unusual to see 3 fight scene in one episode. Even though some of the fight scene are predictable you still would want to see how the fight goes. Also, some fight are pretty intense.
Who should watch this anime?

If this anime was a cuisine/food you can compare it to Popcorn. Popcorn has no meaningful nutrition value and it wont fill your stomach, but if you want something to eat as a way to pass time than this anime will do.
