Christina and Grant are studying Japan in school. They are so excited about the mysterious and exotic country that they talk Mimi and Papa into flying the Mystery Girl airplane to Japan. It all seems so beautiful and serene: the gardens, the cherry blossoms, the beautiful geisha. But what about the very large sumo wrestlers, the samurai swords, and who are those ninja, anyway? The ground is shaking, too—from a rumbling volcano and a tummy-tumbling earthquake! Creepy calligraphy clues lead them on a chase through neon-lit Tokyo, a mysterious Japanese garden and via bullet train to the awesome Mt. Fuji! Grab a ticket and join them for all the fun, frights, and adventure!
