Suntory Holdings Ltd. is poised to raise as much as ¥476 billion by listing shares of its nonalcoholic beverage business in what would be Japan's largest initial public offering this year.

The company has set a tentative IPO price of ¥3,800 per share for the July 3 Tokyo listing, according to a filing Wednesday with the Finance Ministry. The Suntory Beverage & Food unit may sell as many as 125.2 million shares including over-allotment, according to Bloomberg calculations based on the filing.

Suntory Holdings will hold 59.5 percent of the listing unit, said Midori Takahashi, a spokeswoman for the company.
