(c) KADOKAWA / Photography: Yu Tokyo This is the 2nd photo book by Rika Mayama, the oldest member of the idol group Shiritsu Ebisu Chugaku (commonly known as Ebichu), which celebrates its 17th anniversary this year. The shooting location was Thailand, the land of smiles. It captures her natural self, relaxing on Pattaya's beaches and resort villas, strolling through the city, and traveling by train. This photo book, published in her last year in her 20s, captures her "now" – a stoic individual who has diligently pursued idol activities and continuously polished herself to shine powerfully since the group's formation, despite her small stature. Also, don't miss the never-before-seen thrilling scenes, including her first-ever swimsuit and lingerie shots! ◆ Comment from Rika Mayama I am very happy to be able to release my long-awaited 2nd photo book! This time, I challenged myself to wear a swimsuit for the first time. Actually, the light blue swimsuit was for the first shoot, and I wasn't planning to go into the sea considering the subsequent shoots, but I loved the sea so much that before I knew it... (laughs). I had a blast. Also, at my request, we went sightseeing at some Thai-like spots. I was in a cheerful mood, even wearing pigtails, which I rarely do! There are also some shots with giant statues that will bring back nostalgic feelings for Ebichu Family members. I hope you will see me as an idol, embodying the Rika Mayama of the past, and also my life-sized self with the flexibility to embrace the future. Please look forward to it!
