Japanese Aquariums Use Relationship Charts and ASMR to Engage Visitors

Japanese aquariums are utilizing detailed social maps and audio recordings to highlight the unique personalities of their animals to the public.

These strategies transform traditional animal displays into narrative experiences, driving digital engagement and attracting visitors through viral social media content.

Sumida Aquarium, located in Tokyo's Tokyo Skytree Town, displayed the "Sumida Penguin Relationship Chart 2026" on Dec. 13, 2025 ^[1]. The chart tracks the social dynamics of 58 Magellanic penguins ^[1].

The display specifically highlights the interactions between the birds and a keeper named Sato. Livedoor said the chart includes humorous descriptions such as penguins that get angry just by making eye contact or those that are in the process of "training to approach" the staff ^[1].

This approach to animal storytelling is not limited to Sumida Aquarium, as the Kyoto Aquarium has implemented a similar rollout ^[2]. By mapping the complex social hierarchies and personal frictions of the colony, the facility creates a relatable narrative for guests.

Beyond visual charts, auditory experiences are also gaining traction. A video featuring the ASMR sounds of a hippo became a viral sensation on social media ^[3].

TBS NEWS DIG said the hippo ASMR has been well received by viewers who describe the sounds as "healing" or effective for helping them sleep ^[3]. The video highlights a broader trend of using animal-focused sound recordings to tap into the global popularity of ASMR content.

These initiatives reflect a shift in how zoological institutions manage their public image. Rather than presenting animals as static specimens, these facilities present them as individuals with distinct temperaments, and social lives.
