From the Source Campaign' nationwide from Friday, May 1, 2026, to Tuesday, July 7, 2026*¹, to commemorate the 30th anniversary of the launch of its deodorizer and air freshener series, 'Shoshugen'. Since its birth in 1995, 'Shoshugen' has continuously faced the 'sources of odors' in households.

With gratitude for 30 years, 300 people will be gifted 'reset experiences' such as professional house cleaning and esthetic experiences. Furthermore, as a double-chance prize, 300 people will receive a 'Shoshugen 30th Anniversary Appreciation Assortment Set', supporting a daily life where both home and mind are refreshingly organized. *1: The receipt validity period is until Tuesday, June 30, 2026. Campaign website: https://www.kobayashi.co.jp/brand/shoshugen/30th-campaign/ Since its birth in October 1995, the 'Shoshugen' series has been close to Japanese households for 30 years, continuing to face various odors in daily life. In this campaign, with 30 years of gratitude, in addition to approaching the 'root cause of odors', we have selected prizes that can refresh the burdens and stress that accumulate unknowingly in busy days. It contains the desire to deliver an opportunity to comfortably restart daily life by neatly organizing the living environment and guiding the mind and body to a positive state. 'Shoshugen' will continue to support consumers' positive everyday lives by reducing small daily discomforts and refreshing 'odors' and 'minds'. 30th Anniversary Special Site: https://www.kobayashi.co.jp/brand/shoshugen/ ■ Application Period Friday, May 1, 2026 – Tuesday, July 7, 2026*¹ ■ Prize Details A.
