well in general using examples from other articles will not be helpful because there is a lack of consistency in fact the article about kodokan judo is currently at kodokan and itto ryu is currently at itt ry please be aware of the difference though between arts where the name of the martial art practiced such as judo or kenjutsu is a part of the name of the school and where it is just describing the school if it is part of the school's official name it should be capitalized and be included in the name of the article if it is not part of the school's official name it should not even be part of the article's title much less capitalized thus i believe and i could be mistaken that kodokan should actually be moved to kodokan judo while itt ry should stay where it is a good rule of thumb might be if you were to go to japan and look at the sign hanging over the front door what would it say i suppose itto ryu might included kenjutsu after it but certainly any of the comprehensive koryu would have only the name of the school daito ryu on the other hand seems to clearly use aikijujutsu as part of its name there's even a great old photo of morihei ueshiba from the s sitting in seiza in front of a sword stand and a hanging banner that reads in kanji of course daito ryu aikijujutsu regarding the hyphen in aiki jujutsu i may have actually been the one to add that originally it's purely a personal preference issue there are no rules regarding hyphens in hepburn romanization their use is up to the judgment of the writer to include them wherever they help to improve clarity i felt that an english speaking reader with no japanese experience might have a hard time with aikijujutsu because all of the repetitive vowels kind of make the word blur together and it is a logical place to break the word up without making it look like two entirely separate words or putting it another way it makes aikijujutsu readily identifiable as a compound word and clearly shows the two root words i am not at all attached to doing it this way though and would have no problem with them all being changed back to aikijujutsu if anyone feels strongly about it
