| Outline of Final Research Achievements |
Behind the apt use of natural materials is the existence of plant-specific optimized structures. For example, the relationship between the microstructure and physical properties of cherry and birch bark has revealed the physiological function of the bark, which is designed to peel off from the outside as it dries, as well as part of the reason why the bark has been used as a cordage since the Yayoi period. In addition, we proved that the use of ‘O-i-ma-sa' shingles for kokera-roofing, a roofing method for traditional buildings, was the wisdom of our ancestors who utilized the unique cellular structure characteristics of softwoods. Finally, we have tried to design wood materials that respond to the external environment based on these characteristics of optimized structures of wood.

| Academic Significance and Societal Importance of the Research Achievements |
木材の性質や特性についての科学的な知識を持つことは社会にとって非常に有益である。すなわち、木材の性質や特性を理解することで、より効率的な資源利用が可能となり、木材の種類や特性に合わせた適切な加工方法や設計を選択することで、無駄を減らし、資源の節約に寄与することも可能である。また、教育的な面では、優れた木質の特性をわかりやすく説明することで、持続可能な材料選択や環境への配慮を促進する一助となるだろう。最後に、科学的な点では、開発された生物画像に対する情報処理技術は、形態を観察の対象から解析の対象とする意味で、今後多面的な展開が期待される。
