Kokuyo Survey Field Book "Sokuro Yacho"- 3mm Grid Pattern Paper
Kokuyo Survey Field Book, or Sokuryo Yacho in Japanese, literally means “Surveying Field Notebook.” It's often simply called “Yacho” by loyal users. This is a small, pocket-sized, portable, "hard-cover" notebook featuring ultra-lightweight paper.
The paper has a smaller grid pattern on 3mm centers. The notebook measures approximately 3.7 inches wide by 6.5 inches tall and .2 inches thick. This is a very small, slim notebook, perfect for travel notes. There are 40 sheets of paper in each notebook. The original Kokuyo Field Sketch Book cover is green coated board with stitched binding. Brighter colored covers and matching endpapers are newer releases of the original design. Sokuryo Yacho was launched in 1959 especially for the surveyors and civil engineers.
