Nobody talks about this one. A single OVA made by an NPO about saving Japanese agriculture should be a dry policy film, instead it's a genuine cry for food independence that lands with the weight of something fighting for survival. The "American Train" isn't just a metaphor, it's the collapse of an entire nation's ability to feed itself, and the show treats that collapse like a personal betrayal. You watch farmers who know what they're losing, not spokespeople explaining why it matters.
Ikari no Daichi is a single-episode OVA that runs about 90 minutes and works as a documentary instead of a dramatized story. Its subject is Japan's food supply and the steady decline of Japanese agriculture since the 1950s, as Western consumer culture and imported goods pushed domestic farming aside. Along the way it touches on environmentalism and consumerism, drawing its case from documentary records. The film argues for reviving the country's farming so that Japan can produce safe, reliable food on its own soil.
