Field notes
The site groups its notes into categories such as space, sea and fishing, living things, technology, history and culture, and nature. Its reading-level control is unusually concrete: readers can select lower elementary, upper elementary, or middle-school Japanese, and the browser retains that preference for later articles. The administrator explicitly cautions that the writing records the day’s understanding rather than presenting textbook-level certainty. Recent entries include explanations of water viscosity, convenience-store history, fish-name origins, and crow cognition.
