| About 'Thanks Mama Forum'
The 'Thanks Mama Forum' is a childcare support event regularly held by Ariake Garden with the aim of being a 'commercial facility close to child-rearing'. Since its first event in February 2024, the number of visitors and sponsoring/exhibiting companies has been increasing year by year, receiving highly positive feedback from various quarters.
Our company has consistently focused on building a community for the parenting generation in the local area by continuously conducting large-scale events for children. Through the 'Thanks Mama Forum', we promote initiatives that listen to the voices of the parenting generation by providing a space where they can share concerns and anxieties about childcare, as well as share the joys of raising children.
Moving forward, with Ariake Garden as a base, we will continue to contribute to community building that supports child-rearing, serving as a 'place of encounter and co-creation' connecting the parenting generation, the local community, and companies/organizations.
