Venue

Ibaraki Kogen Country Club

豊能郡, Japan

The Ibaraki Kogen Country Club is situated in the northern Osaka region, positioned at an elevation of 680 meters near a mountain summit. The course was developed by clearing hilly terrain, resulting in a layout that is notably flat for a high-altitude facility. The 18-hole, par-72 layout is divided into two distinct halves. The front nine is characterized by wide fairways that invite powerful, long-distance shots, while the back nine presents a more varied and strategic challenge requiring precise ball placement. The front nine totals 3,327 yards from the back tees, featuring a mix of par-4s, a par-3, and two par-5s. The 1st hole is a demanding 431-yard par-4, while the 3rd hole offers a longer 503-yard par-5. The short 2nd hole is a 145-yard par-3, and the 7th hole measures 158 yards. The back nine covers 3,407 yards from the back tees, including a significant 541-yard par-5 at the 16th hole. The 14th hole is another long par-5 at 514 yards, and the 13th hole is a 443-yard par-4. The 11th hole is a 200-yard par-3, and the 17th hole measures 186 yards. The course is equipped with GPS navigation in all carts and utilizes specific local rules, such as treating drainage ditches as immovable obstructions and defining out-of-bounds with white stakes. The JGA Course Rating is listed at 73.2 with a Slope Rating of 142 from the back tees. The facility hosts various open competitions and member events throughout the year, including the Motosakizaka Cup and the Bridgestone Cup. The club maintains a practice facility and a clubhouse with dining options for its members and guests.
