The price has been fixed for Japan's biggest ever listing.
The country's third largest mobile phone and network provider Softbank is aiming to sell at 1,500 yen per share, which alongside the sale of 160 million extra shares, would raise $23.5 billion.
That will make it almost as big as Alibaba's ipo in 2014 - which was the world's largest.
Softbank, which controls the world's biggest tech private equity fund plans to use the capital on startups such as Uber.
The company is listing with all the bells and whistles, it's taking out TV adverts to spur national interest.
And it will have its work cut out.
Last week, customers were left without the use of their mobile phones after a four-hour outage.
Softbank said it did not expect that to affect its earnings or dividend forecast.
But another issue is also being closely watched - Huawei and the arrest of its chief financial officer in Canada.
Softbank has a long relationship with the Chinese equipment provider and has worked with them on trials of 5G technology.
Sources have told Reuters Japan's government is considering banning Huawei and ZTE products from government procurement.
And Japan's big three telecom operators are also reportedly planning not to use current equipment and upcoming 5G gear from the Chinese firm.
