◾️ Regarding the Top Sponsor Agreement
The top sponsor agreement was realized through a partnership that resonated with the facility's vision of fostering connections with diverse living creatures and providing opportunities for learning, as well as Maruha Nichiro's vision of connecting the richness of the ocean to the future. Through this partnership, we will also explore opportunities for visitors to experience the richness of nature, with the ocean as a starting point.

Maruha Nichiro Comment
We are extremely pleased to be able to participate as a top sponsor for "Wonderia Yokohama Supported by Umios." Our company will change its name to "Umios Co., Ltd." on March 1, 2026, and under our purpose "For the ocean, for life," we aim to be a solutions company that benefits both people and the planet through food, with our value creation centered on the ocean. The concept behind "Wonderia Yokohama"—to provide opportunities to discover new aspects of living creatures and nature through immersive experiences utilizing digital technology, thereby enriching our daily perspectives—resonates with our own deep regard for the ocean and nature. Together, through this facility, we will create opportunities for many people to feel the richness of nature and contemplate a sustainable future.

◾️ Unveiling of Six Zone Names and New Visuals
"Wonderia Yokohama Supported by Umios" is an immersive experience facility that delivers encounters with wonder and mystery alongside lifelike visuals. The facility is comprised of six zones, each with a different theme, allowing visitors to enjoy encounters with creatures and nature that are rarely experienced in daily life. The names of all six zones have now been released.

Zone Name | Stage of the Zone
Zone 1: Shifting Seasonal Colors | Highland
Zone 2: Dive to Blue | Deep Sea
Zone 3: Mimicking Forest | Primeval Forest
Zone 4: Touch the Darkness, Dance with Light | Cave
Zone 5: Dancing in the Sky | Lake and Sky
Zone 6: Into the Wonder | City

For example, Zone 2, "Dive to Blue," is set in the deep sea, offering an experience of diving from above the sea surface into the deep blue of the ocean depths. Zone 5, "Dancing in the Sky," depicts the transition from a lake reflecting the sky to the vast expanse above.
