日本の森林管理政策において、林業の採算不振による所有者の「山離れ」は21世紀となってからも引き続き大きな課題である。政策的な対応として、2019年度より市町村による私有林の公的管理を推進する「新たな森林経営管理制度」が導入された。本制度の是非、さらには制度の前提である所有者の「山離れ」の現状については議論がなされている。一方、日本の国土の約７割を占める森林の管理を考えるうえで、その過半（2012年時点で58％）を占める私有林の管理が重要であることは言うまでもない。
　新たな森林経営管理制度では公的管理の推進がうたわれてはいるが、私的財産として森林を所有する森林所有者の意向はその公的管理の前提である。したがって、所有者が自身の森林所有についてどのように感じ、考えているかを把握することは、今後の政策を検討するうえで必要であろう。また、所有者による自発的な森林管理は、環境に配慮した、きめ細かな管理を期待できる点で理想的な姿とも考えられ、所有者が森林に向き合う姿勢の把握はこの点からも重要である。さらに、新たな森林管理制度の財源としては、森林環境譲与税が新たな国民負担をともなって市町村、都道府県に配分されることになる。納税者への説明責任の点からも、森林所有者の意思、それに伴う所有者の果たす役割は明確にされなくてはならない。
ここでは、森林所有者にとっての森林にかかわる主観的幸福度（森林幸福度）を非所有者との対比に基づいて検討する。昨年度の本大会では自然資本、人工資本と森林幸福度の関連について報告したのに対し、今回は森林所有が森林幸福度に及ぼす影響を検討する。

Community actions against anticommons in contemporary Japan: Case studies of former commons forests International conference

Over the past few decades, many Japanese forest owners and communities have suffered from the outcomes of anticommons policy. Since the Edo Era (17th through 19th centuries), many Japanese commons forests have been subdivided and placed under private ownership.
Due to recent unfavorable conditions for timber production in Japan, individual owners of the subdivided small forests (carved out from former commons forests) have lost interest in forestry, resulting in unclear borders. Many owners have relocated outside the villages and/or have passed the land down through generations, resulting in unknown ownership. Such ambiguity regarding forest ownership hinders further forest management activities.
Fortunately, there are several ways to ameliorate the anticommons phenomenon in Japan, as illustrated by these examples. 1) Despite the expense, a residents’ association successfully re-appropriated co-ownership land by “technically” suing the current respective co-owners. 2) Some residents’ associations collectively manage subdivided forests as one unit to reduce the damage caused by animals such as wild boars or deer. However, the units are still legally separate and owned by individuals. 3) A residents’ association stipulated that a vacating resident must sell her forest to the remaining residents. This type of rule (iriai), though alien to the modern notion of permanent ownership, was once customary in Japanese villages.
These three cases show how motivations, other than profits, could help address the anticommons phenomenon. These motivations include the intent to keep the community’s holding intact in the event of consolidation at the municipality level, to protect the land against pest animals, and to keep the community’s drinking water pure. These community actions against anticommons were made possible by support such as funding or external expertise. Funding from outside sources, such as rent revenues from a resort company renting the commons land or subsidies from the national and local governments, were indispensable for carrying out some of these communities’ actions. In some of these cases, external administrative and legal expertise, such as employees of local governments, a forestry cooperative, or lawyers, was an important factor in making these actions possible.
In addition, the existing challenges of these communities should be noted. The first community still faces depopulation and is examining how to deal with this problem. The applicability of the second case (community-wide forest management to reduce damage by wild animals) is limited to forests with relatively low economic values. It is difficult to manage separate, private forests with relatively high economic values as one unit since the owners have high stakes in their properties. Considering these challenges, researchers and policy makers should strive to find more innovative solutions for addressing them.

Impacts of modernization policy on the management of commons forests in Japan: A statistical analysis of individual data International conference

Venue：Utrecht, The Netherlands

After World War II, Japan's policy makers believed that common forests were underutilized because of their legal status and organization method under customary iriai-type ownership and that modern ownership in the form of group ownership, such as forest producers' cooperatives, or as individual, separate ownership, would improve the situation. Thus, the Commons Forests Modernization Act of 1966 was enacted, following successive modernization policies since the Meiji Restoration in 1868. We evaluated the impacts of the past modernization policies on the management of commons forests by statistically comparing the performance of modernized and non-modernized forests based on the 2000 Forestry Census. The performance measures for comparison included planting, weeding, thinning, and harvesting activities among others. We found less modernized, customary holdings are more active in tending activities such as weeding and thinning, while modernized holdings may have an advantage in timber sales.
