Japan left captain Michael Leitch out of their starting team for Saturday's Rugby World Cup clash with Ireland as a fit-again Amanaki Mafi took his place in the back row as one of five changes from their opening day win over Russia.
With winger Kenki Fukuoka still unavailable with a calf injury, Ryohei Yamanaka comes in at fullback as Will Tupou shifts to the wing and Lomano Lemeki drops to the bench.
Elsewhere in the pack, Luke Thompson replaces Wimpie van der Walt in the second row, Jiwon Koo and Shota Horie come into the front row and Kazuki Himeno moves to flanker to make room for Mafi at No.8.
South Africa-born flanker Lappies Labuschagne will captain the side in Leitch's absence.
