India's elusive hunt for a world champion in the sport continues as Japan got theirs after a gap of 40 years.
Either way, it will be historic regardless of the outcome.
"Well played @Pvsindhu1! We are proud of your game at the @2017BWC finals".
Who has the advantage?
PV Sindhu won their last showdown in the first round of the 2017 Singapore Open Superseries with a tight 10-21, 21-15, 22-20 scoreline.
It is yet another final for the silver medalist from Rio, PV Sindhu.
Sindhu has a head-to-head record of 3-3 against Okuhara, suggesting that the match could go either way. Their matches tend to be tight with only one not going the distance.
Currently, Sindhu is fourth and has a career-best of second rank.
In the decider, Saina grabbed an early 3-1 lead but Okuhara soon started dominating the rallies.
This will be a game of contrasting styles.
A match between two fighters who didn't give up till the last point.
India has won one silver (through Saina in 2015) and four bronze in the World Championships before this Glasgow edition.
While both players looked out of breath and struggled to move, Sindhu got a bit more exhausted than the Japanese and that led to the end result.
"I should not have gone to Rio", Saina had stated after her match against Gilmour.
Saina took Okuhara out with a lovely misleading shot to race to an 8-2 lead. She was also pepped up playing in front of her home crowd and she wanted to do well as this was a medal round. Nevertheless, Saina, along with PV Sindhu, created history by helping India clinch two medals in the same edition of a World Championships.
Okuhara continued to move ahead, reaching 18-14 after winning 10 of the 13 points after the interval. It was a picture of utter ruthlessness and determination. Her smashes were powerful and overpowered the opponent by the brilliant cover up on the net.
But kudos to both, who made sure they drained every speck of energy from each other to give the spectators exactly what they had paid for.
