Filmmaker's book captures lives along China's Yangtze

Starting from Shanghai, he traveled upstream through cities like Wuhan and Chongqing, capturing footage for the documentary and compiling his observations into the book, which delves into the behind-the-scenes stories of the documentary.

"I told stories about China even when I lived in Japan, and I continue to do so now. I want to showcase the objective reality of China and the Yangtze River culture to the world," Takeuchi said.

"As I document, I also seek to understand China better. Next, I will film the Yellow River," he said.
