### Check-in and Entry

Participants entered the aquarium upon check-in.

Initially, attendees appeared slightly nervous, but their mood was quickly lightened by guest MC Offside Nii-san, a popular YouTuber known as “the man who stops depopulation through fun.”

Additionally, a special dolphin program exclusively for participants, set against the backdrop of sunset, greatly energized the atmosphere.

### Start of Conversation Time

Following the dolphin program, the conversation session began.

Participants enjoyed conversations with potential partners at iconic spots such as the large tank “Watatsumi no Keshiki” and the popular photo zone “Uzushio no Keshiki.”

The dimly lit interior and the shimmering light from the aquarium tanks created a dreamy, romantic ambiance, enhancing the sense of a once-in-a-lifetime experience.

### Encounter-Supporting Activities

The event featured a variety of interactive content to foster connections, including the “Matching Rally” where participants completed challenges with opposite genders, the “Fish Talk Lounge” sparking conversations around marine life, and the “Heartbeat Photo Spot” allowing couples to take commemorative photos together.

For the Matching Rally, sponsor Aiwakou Co., Ltd. provided chocolate marshmallows as prizes. Some male participants even gifted these marshmallows to women as icebreakers for conversation.

## Participant Feedback

Post-event surveys showed that over half of the participants gave high ratings, indicating extremely positive feedback on their overall experience.

Participants shared the following comments:

- "The unique aquarium setting made it easy to start conversations."
- "I enjoyed the rare experience of being in an aquarium at night."
- "It was my first time visiting at night, and the atmosphere was refreshingly different."
- "Even just watching the fish was fun, but the structured activities naturally encouraged interaction with the opposite sex."
- "We hope you’ll host a similar event at the same scale again!"
