Boku ga Mita Katta Aozora, the official rival group to Nogizaka46 produced by Akimoto Yasushi, celebrated their third anniversary with a major milestone: their first outdoor solo concert at Lake Kawaguchi Stella Theater in Yamanashi Prefecture on June 20.

The venue held special significance for the group. Lake Kawaguchi served as their "starting point," hosting training camps both before debut and ahead of their first national tour. Five members—Iwamoto Riho, Kanazawa Ami, Kudo Yui, Hayasaki Suzuki, and Yanagibori Hanare—represented the group at press interviews before the show, reflecting on the journey that brought them to this moment.

This concert marked the finale of their spring national tour, which kicked off in March from Tokyo and traveled to six cities nationwide. Vice-leader Yanagibori expressed relief at reaching the final with all 20 members intact, while Iwamoto acknowledged that ticket sales fell short of their full-capacity goal but noted meaningful growth across the team. "This tour helped us develop flexibility in how we perform," Hayasaki added, describing how members had moved beyond simply executing given choreography.

Weather proved challenging—rain forced organizers to close the venue's roof, though members insisted the outdoor atmosphere remained intact. Iwamoto joked about the setback: "Next time, we're climbing Mount Fuji," drawing laughs from reporters.

The group, which debuted in August 2023 after auditions drew over 35,000 applicants, has released eight singles in three years. Their latest, "FUNKY SUMMER," features Kanazawa as center. Last year's 7th single "Are wa Fairy" marked their commercial peak with 120,000 first-week copies sold.

Looking ahead, members balanced confidence with self-awareness. Yanagibori noted their strength in adapting to diverse song styles but acknowledged uncertainty about their group identity. "Right now, our approach is giving our all to what's in front of us," she said. The group's concrete goals include performing at arena venues and eventually Japan's largest concert halls, with Iwamoto declaring: "We want to become synonymous with idols."

Despite missing their hoped-for Mount Fuji views, the performance underscored a group finding its footing through persistent touring and fan connection.
