This design notebook is full of energy and humor, featuring a vibrant illustration of delicious fish swimming leisurely in the ocean, adorned with powerful calligraphy reminiscent of Japanese culture. A new design has been added: the beautiful salmon-pink salmon. A familiar and delicious fish on Japanese dinner tables, salmon are considered a symbol of success because they are born in rivers, travel to the open sea to grow, and then return to their home rivers. They have also been cherished as a lucky charm, as the name "sakeru" (salmon) sounds like "sakeru," meaning to ward off misfortune. One special fish in the school is a male. Its body is yellow, characteristic of the breeding season, with red markings and a handsome face with a pointed snout. This fun notebook is filled with playful details, such as recipes for delicious Japanese fish dishes and accentuating wave-shaped ruled lines. The paper inside is suitable for writing, with minimal ink bleed-through and bleeding.
