"I'd like to think there's a bit of feel in and around the whole situation."
World Rugby confirmed the hearing would take place in Tokyo on Monday night.
Ireland head coach Joe Schmidt said Aki was "devastated" after he was sent-off for the tackle against a player of his fatherland, Samoa.
Meanwhile, Samoan coach Steve Jackson was sympathetic towards Aki following the match, adding he shouldn't be suspended for the tackle.
"We'll do everything we possibly can from a Samoan perspective to make sure that he gets on that field next week," Jackson said previously.
"If you look at Bundee's tackle again, UJ came with the ball at pace and I think he only had two or three metres to make a decision as to what sort of tackle he might put in.
"Was there malice in Bundee's tackle? No, he's just physical in the collisions, being a Samoan boy."
Ireland dropped to second on the ladder of Pool A after hosts Japan defeated Scotland 28-21 last night, setting up an interesting run to the finals.
In a quarter-final matchup few would have predicted, Ireland will face the All Blacks on Saturday at 11.15pm.
The match will be just the second time the two sides have met at the World Cup, following a 1995 pool play clash which New Zealand won 43-19.
