I happened to had the experience to take a limited train with many images from KAIYUKAN (a big Aquarium in Osaka) . It is limited until next April.
The train is full of words of the sea and signs of life scattered in various places.
"This collaboration project was born out of our desire to make passengers feel the beauty of the ocean and the wonder of living things during their daily routine. The car is decorated throughout with colorful sea anemone motifs, petite messages conveying the wonders of Kaiyukan's wildlife, artworks and more."
