On the scales both men were dead on the limit of 115lb for the bout.
For Inthanon the weight his highest recorded weight, marginally higher than he was for his world title bout with Kohei Kono earlier this year. For Mukai the weight is his lightest since a 2014 win over current OPBF Bantamweight champion Mark John Yap, when Mukai was 114¾lbs, and sees him dropping back down in weight following a stint at Bantamweight.
At the weight in both men looked in great shape and it seems clear that the title means a lot to both men, so we're expecting to see a really goof bout, but one that is likely to go the 12 round distance with neither man known for having much in terms of power.
