Up to 53% OFF for Children and 28% OFF for Adults! "Iko-yo Special Day" to be Held at Hakone Kowakien Yunessun!

The children's outing information site "Iko-yo" (operated by Actindi Inc.) launched a new initiative in September 2025 called the "Family Memory Support Project."

This project aims to enrich the time children and their families spend together and help them create irreplaceable "memories." In recent years, the environment surrounding child-rearing has changed significantly due to factors such as the increase in dual-income households, the diversification of lifestyles, the advancement of digitalization, and rising prices. Amidst these changes, Iko-yo believes that "irreplaceable experiences for children and memories with family are the essential foundation for future growth and family bonds."

Therefore, through this project, we will work with facilities across the country that share this sentiment to provide opportunities for parents and children to share wonderful times and deepen their family bonds.

For this installment, we are holding a special discount campaign at "Hakone Kowakien Yunessun," a popular hot spring theme park in Kanagawa Prefecture that has agreed to support this initiative.
