Obagi 25th Anniversary: POPUP Event "#That'sWhyI'mObagi POPUP Event ~Vitamin C Stand Where You Can Choose According to Your Needs~" to be Held in 5 Cities Nationwide, Offering Personalized Care Through AI Skin Measurement x Product Experience

Rohto Pharmaceutical Co., Ltd. (Headquarters: Osaka, Osaka Prefecture; President: Hidetoshi Segi) will celebrate the 25th anniversary of its skincare brand "Obagi," which aims for healthy and beautiful skin, by holding an experiential event titled "#That'sWhyI'mObagi POPUP Event ~Vitamin C Stand Where You Can Choose According to Your Needs~" in five cities nationwide (Tokyo, Nagoya, Sapporo, Osaka, Fukuoka) starting in May 2026. In recent years, with the diversification of skincare information and product choices, the concern of "not being able to confidently choose items that suit my skin" has been increasing. Obagi has consistently focused on "what works for the skin," backed by years of cultivated dermatological research knowledge. As it reaches its 25th anniversary, with gratitude to customers who have supported it and a desire to continue being a brand that stays close to its customers, Obagi has adopted "#That'sWhyI'mObagi" as its catchphrase and is implementing initiatives that value customer voices. ■ About the experiential event "#That'sWhyI'mObagi POPUP Event" At this event, visitors can experience a series of steps from visualizing their skin condition to product experience, starting with Obagi's unique AI skin measurement "AI Skin Partner." Based on the measurement results, visitors can try products mainly from the C Serum series, and through the provision of Vitamin C drinks, they can experience "choosing skincare that suits them." In addition, Rohto Pharmaceutical staff will guide visitors on product features and how to choose, and there will also be SNS posting campaigns and photo spots, creating a space where visitors can experience the world of "#That'sWhyI'mObagi." This event aims to provide an opportunity for both long-time users and those new to Obagi to truly feel the brand's value. ■ Event Overview Event Name: #That'sWhyI'mObagi POPUP Event ~Vitamin C Stand Where You Can Choose According to Your Needs~ Content: AI skin measurement, product touch-ups, Vitamin C drink and product sample provision, mirror photo spot, SNS posting lottery How to participate: Walk-ins / Free May 9 (Sat) & 10 (Sun), 2026, 11:00-21:00 @MIYASHITA PARK South 2F Atrium (6-20-10 Jingumae, Shibuya-ku, Tokyo) Approx. 3 minutes walk from "Shibuya" Station, approx. 8 minutes walk from "Meiji-jingumae " Station Exit 7 May 23 (Sat) & 24 (Sun), 2026, 10:00-19:00 @KITTE Nagoya 1F Atrium (1-1-1 Meieki, Nakamura-ku, Nagoya-shi, Aichi) Approx. 1 minute walk from "JR Nagoya" Station May 30 (Sat) & 31 (Sun), 2026, 11:00-19:00 @COCONO SUSUKINO 3F Indoor Space (4-1-1 Minami 4-jo Nishi 4-chome, Chuo-ku, Sapporo-shi, Hokkaido) Approx. 1 minute walk from "Susukino" Station June 13 (Sat) & 14 (Sun), 2026, 10:00-19:00 @Osaka Station City North Gate Building 2F Atrium Plaza (3-1-3 Umeda, Kita-ku, Osaka-shi, Osaka) Approx. 1 minute walk from "JR Osaka" Station June 20 (Sat) & 21 (Sun), 2026, 10:00-19:00 @Solaria Plaza 1F Event Space "Zephyr" (2-2-43 Tenjin, Chuo-ku, Fukuoka-shi, Fukuoka) Approx. 1 minute walk from "Nishitetsu Fukuoka (Tenjin)" Station *Vitamin C drinks and samples are limited to one per person.
