Free announcers Rie Mochizuki and Aiko Kaido appeared in Tokyo in early June to promote a new Saint Force photo book [1].

The event marks the 30-year anniversary of the talent agency and highlights the enduring public appeal of its high-profile announcers.

The publication is referred to as the “Saint Force Official Book 2026-2027” [1], though some reports identify it as the 30-year anniversary memorial book “Jewels” [2]. To support the release, the agency organized a talk event spanning six days [1].

During the promotional appearances, Mochizuki and Kaido shared reflections on their careers and the photo shoot process. Mochizuki said that some of the poses she worked hard on were not ultimately used in the final book [1].

Mochizuki also commented on the terminology used for the event. She said, "The title of the talk show said 'veteran' (kosan). I wondered what kind of veteran—whether it meant being with Saint Force for a long time, or a veteran in terms of age."

Kaido, who is 40 years old [3], reacted to the discussion of tenure and age by saying, "So young" [3]. Mochizuki's age is reported between 52 and 54 years [2, 4].

The promotional events took place throughout the first half of June, with reports surfacing on June 5, June 6, and June 12 [5, 6, 7]. The appearances served as a celebration of the agency's three decades of influence in the Japanese media landscape.

“The title of the talk show said 'veteran' (kosan).”

The release of the anniversary book and the accompanying tour underscore Saint Force's strategy of leveraging the 'free announcer' brand. By positioning veteran personalities like Mochizuki and Kaido as timeless figures, the agency maintains its market relevance and celebrates its institutional history within the Japanese entertainment industry.
