Then have one of the normal TNA ppvs be a follow up to it with some NJPW guys invading TNA, etc.
Ok go set that up. It's easier said than done.
Don't use it to book a proper domestic TNA/NJPW pay per view. Just use it to furthur or start angles in TNA, like wrestler A giving wrestler B shit for losing a match at the Tokyo Dome or have your top TNA guys do the whole partner gets mad at other partner for costing them the match at the big show.
