His final round of 69 saw him improve from 52nd to 33rd on the demanding Fukizakura Country Club layout.
Bransdon, who is in his rookie season on the Japan Tour in 2017, has made six of eight cuts thus far but is still very much on the fringe of retaining his card for 2018.
Bransdon is currently in 67th position on the money list and needs to be inside the top sixty to be assured of full status next season.
Most of his earnings came when finishing 4th at the Kansai Open in May but he is finding his feet amongst the nuances of playing the Japan Golf Tour and his good finish today is further evidence of that.
There are still ten or eleven events which he is likely eligible to play so there is plenty of time to advance his cause.
Bransdon was the only Australian to make the weekend and gets another opportunity in two weeks’ time when the Japan Tour moves north to Hokkaido for the ANA Open.
The next event on the Japan Tour however is the completion of the lucrative ISPS Handa Match Play Championship in Chiba next week, the first half of which was completed a month ago.
Won Joon Lee, Matthew Griffin and New Zealander Michael Hendry remain alive into the Round of 32.
This week's event was won by 35 year old Korean Hyun Woo Ryu who won his second Japan Tour event five years after his first.
Ryu won in a playoff over Satoshi Kodaira and Seung Su Han.
