＊Sokuryo Yacho=a surveying field notebook, “Yacho” for short.

Yacho the surveying field notebook unchanging for more than 50 years

1959年発売の測量野帳は、発売の10年前（1949年）に測量法が制定されたのをきっかけに、ニーズが増大した測量業務の現場の声を反映し開発されました。コクヨでは、ノートなら「ノ」で始まる品番、製図用品なら「セ」で始まる品番がつけられています。測量野帳は、ノートのように見えますが、「セ-Y1」などのように製図用品の品番が付いています。 Released by Kokuyo in 1959, 10 years after the first national Survey Act was enacted in Japan, Sokuryo Yacho (=測量野帳, literally meaning 測量=surveying/measuring, 野帳=field notebook in Japanese), was originally designed and developed to meet the demands of surveyors and civil engineers to make their works easier and more streamlined as there were more and more surveying operations they had to do. Kokuyo, uses the product number starting with “NO” as in notebooks, and “SE” as in "seizu-yohin,"meaning architectural drawing instruments. Sokuryo Yacho is a notebook, but it has the product number “SE-Y1” as it is considered more as a technical instrument.

測量野帳は発売から50年以上が経過しました。しかし、品質改善のための仕様変更があった以外ほとんどデザインが変わらない珍しい商品です。 It’s been more than 50 years since the first launch of Sokuryo Yacho. However, it is one of KOKUYO’s rare products whose design has not changed over years.

その後、屋外での利便性を高めるために、雨に濡れても大丈夫な合成紙のウォータープルーフタイプを追加。
このタイプは、落としたときに、見つけやすいブライトカラーを表紙に採用しています。

Newly added waterproof type uses synthetic papers so that the users can use the notebook under the rainy weather. Bright colors stand out in other objects and can be easily spotted.

中紙に樹脂ベースの合成紙を使用。一般的な耐水・撥水紙よりも水や汚れに強く、破れにくいので、屋外・雨天などのハードな現場で活躍します。
The resin based synthetic papers inside have higher water/dirt-proof and tear-resistant properties than ordinary water-resisting/ repellent papers, and are suitable for the use in the open air or under rough weather.
【耐水比較】
紙の上に水を1滴垂らし、その後の紙の変化を比較 [Comparison on Water resistance] to compare changes of the before and after putting one drop of water on the paper

表紙にも樹脂を使用し、立ったままでも書き込みやすいしっかりした厚さ（0.75mm）を実現しました。 Thickness (0.75mm) of the polypropylene cover makes it easy to writie without a board desk.
