Maui Inflatable Rental Experts

Emerging from challenging backgrounds and embracing early parenthood, we centered our lives on our five children. Initially, we worked as delivery drivers for a company when our fourth child was just 3 years old.
In 2010, we took the leap into entrepreneurship and started our own company, Keiki Castles, which opened new doors and opportunities for us as business owners. Following the birth of our fifth child, we sold our initial business and established Jumping Js.
Our company has consistently been inspired by our children, which is reflected in its name (all our children’s names start with J) and its mission. Making other children and families happy is our way of giving back to the community and putting smiles on our own children’s faces.
For over a decade, we have been a local, family-operated company dedicated to ensuring our customers’ safety and success while having a great time. At Jumping Js, we specialize in inflatable rentals, including bounce houses and waterslides, providing top-quality, affordable options for families across Maui.
The New Generation Of Maui Inflatable Rental Experts

As we grew older and our kids matured, we realized that maintaining the same demanding pace was no longer sustainable. The shift began when our third daughter entered a new chapter in her life, starting a relationship with her boyfriend. Together, they embraced the opportunity to work for Jumping Js, becoming the new generation of “Maui Inflatable Rental Experts”.
They took on critical responsibilities, including delivering, setting up, breaking down, and cleaning all our equipment—everything from bounce houses to water slides.
Their dedication ensured that every rental was not only clean and ready for use but also remained affordable for our customers, helping to uphold the reputation we worked so hard to build.
Today, as we focus on ongoing maintenance and preserving the quality of our services, we are also preparing for the future. With great pride and trust, we’re in the process of “handing off” the business to our third daughter and boyfriend, who have demonstrated the passion and commitment to continue the legacy of Jumping Js.
In the picture, they represent the next chapter of our family’s story—a blend of hard work, family values, and dedication to serving our community.
