Oishi invites everyone to celebrate its 27th anniversary with the “Oishi 9.9” day of sharing happiness. Enjoy a second buffet seat or second a la carte dish for only 27 baht at 165 Oishi branches, while part of the campaign’s proceeds will be donated to share happiness and give back to society.
Marking the 27th anniversary, Oishi Holding Company Limited is redefining celebration with the theme “Every ‘give’ creates more happiness,” expressing gratitude for customers’ ongoing support and trust. This anniversary shifts from simply offering special privileges to inviting everyone to join in giving and creating good for themselves, those around them, and society.
The customer-focused activity kicks off with “Oishi 9.9” a day of sharing happiness (GIVE MORE, SHARE MORE), inviting customers to bring special people, family, or anyone they wish to share good times with, to celebrate Oishi’s 27th anniversary on 9 September 2026 at 165 participating Japanese restaurants in the Oishi group. Oishi believes that “happiness does not diminish when shared; it grows when passed on.” This occasion is more special because every shared meal also benefits society beyond the dining table by linking each redemption to social contributions.
The highlight of “Oishi 9.9” is combining two key numbers of the anniversary—“9.9” (9 September) and “27 years”—into a sharing mechanism allowing customers to celebrate and give simultaneously. This applies only on 9 September 2026 through two options:
For every redemption of the “Oishi 9.9” promotion, whether the second buffet guest or the second dish, the 27 baht payment from each right will be collected and donated to charitable organizations through the “Give” project, aiming to create benefits and spread happiness to people in society.
Thus, a single celebratory meal on 9 September will share happiness on two levels simultaneously: first, “Share with Someone You Love” by sharing food and joyful moments with your companion; second, “Share with Society” by transforming your participation into a contribution that benefits others in the community.
This activity reflects Oishi’s social marketing approach, linking marketing efforts with tangible social value. The celebration thus gains meaning not only for the brand or customers who receive privileges but also opens the door for customers to join in “giving” through simple acts: spending time together, sharing meals, and passing happiness from their table to others.
Beyond the 27th anniversary, Oishi looks to establish lasting significance for “9.9” by developing 9 September into “OISHI DAY” – Oishi Day... A Day of Giving. On this day, Oishi invites employees, customers, and everyone to join in doing good and sharing happiness, so that Oishi’s birthday celebration each year is not just a day for well wishes but a day when Oishi and all join together to give back to society.
Ms. Sasai Tangdechahirun, Managing Director of Oishi Holding Company Limited, concluded: “Over 27 years, Oishi has grown thanks to the support and trust of our customers. On this anniversary, we want to transform Oishi’s birthday from a day of receiving well wishes to a day when everyone joins in giving and sharing happiness back with society. We believe every act of giving, big or small, creates happiness that spreads beyond. This is our intention to develop 9.9 into ‘OISHI DAY’—a day of giving and sharing happiness where Oishi, customers, and society grow sustainably together.”
The more you share, the more happiness grows. On 9 September 2026, invite special people to celebrate “Oishi 27 Years” with “Oishi 9.9,” the day of sharing happiness (GIVE MORE, SHARE MORE), at 165 participating Oishi Japanese restaurants, turning every shared meal into a meaningful act of giving that spreads happiness to society.
