【Rich and Delicious, Now Stronger!】Power-Up with Intense Flavor and Bold Texture — A New Generation of Potato Chips That Deliver an Instant Mood Boost with Every Bite! Koikeya Strong Gets a Full Makeover with Triple-Seasoning and Thick-Cut V-Cut Potatoes

Koikeya Co., Ltd. (President: Akira Sato) is fully revitalizing its 'Koikeya Strong' brand, launching three new products — 'Koikeya Strong Spicy Lemon,' 'Koikeya Strong Sour Cream Onion,' and 'Koikeya Strong Bold Nori' — on June 15, 2026 (Monday), initially at convenience stores nationwide, followed by supermarkets and other general retail channels on June 29, 2026 (Monday).

'Koikeya Strong' is a premium potato chip brand known for its 'triple seasoning (※1)' and 'thick-cut V-shaped potatoes,' delivering a rich, satisfying snacking experience. A recent internal survey (※2) of snack consumers revealed strong appreciation not only for its intense flavor and substantial texture but also for its emotional benefits, with many citing 'stress relief,' 'mood enhancement,' and 'fatigue recovery' as key reasons for consumption. This insight confirmed that the brand’s signature 'richness' resonates deeply with consumers seeking emotional release.

This revamp maintains the brand’s uniquely intense flavor while enhancing it with sharper accents of spiciness and acidity, making the chips even more addictive and irresistible. As a flagship flavor symbolizing the relaunch, 'Koikeya Strong Spicy Lemon (Shin Lemon)' — centered on the refreshing 'spicy and sour' profile — joins the lineup as a new staple.

The packaging has also been completely redesigned to maximize the appeal of 'richness × stress relief.' Featuring dynamic food photography and vibrant colors, the new design embodies the addictive taste and emotional release, creating an intuitive, eye-catching experience that invites immediate purchase. Additionally, the 'Spicy Lemon' variant, perfectly suited for early summer with its 'irresistibly tangy and spicy' profile, will launch with special packaging featuring the 'Heatstroke Prevention Awareness Project Logo (※3).'

A new TV commercial showcasing the full relaunch will air soon. Try the new 'Koikeya Strong' — where rich flavor meets bold satisfaction!
