Japan's chances of playing in next year's expanded Super Rugby series remain uncertain.
They are inked into a draw which has been shown to other sides, the broadcasters and financial partners and Sanzar hopes to make a more concrete announcement next week.
Until then Japan's involvement in an expanded Super 18 series is a maybe, maybe not situation.
Sanzar executives held another telephone hookup yesterday to talk through developments and NZR chief executive Steve Tew said they still needed more information from the Japanese franchise.
They were working "very hard" to take their spot in the 2016 competition alongside other new entrants from Argentina and South Africa.
