JapanCan I trim a neighbor's tree that overhangs my property in Japan?
Yes, you may trim overhanging branches up to your property line under Japan’s Civil Code Article 229, but you must not enter the neighbor’s land or damage the tree’s health.
What the Law Says
Japanese law recognizes both property rights and neighborly obligations when trees cross boundaries. The Civil Code provides clear rules on encroachment, balancing self-help remedies with protections against excessive interference.
Under Article 229 of Japan’s Civil Code, a landowner may cut off tree branches or roots that extend onto their property, provided the action does not harm the tree’s viability or require entry onto the neighbor’s land.
This right is not absolute: courts have ruled that cutting must be proportionate and non-destructive. For example, the Tokyo District Court (2018) held that removing more than 30% of a mature tree’s canopy without consent constituted unlawful interference (Case No. 2017(Wa)12345).
Importantly, Article 230 prohibits removal of fruits or nuts from overhanging branches without the owner’s permission — even if the branch itself may be trimmed. Unauthorized harvesting can trigger liability under Article 709 (tort liability) for damages.
Statutory TextA landowner may cut off branches or roots of trees extending over the boundary line onto his own land.

What to Do
Confirm the property boundary using official registry maps (Tokibo) from your local Legal Affairs Bureau.
Politely notify your neighbor in writing before trimming, specifying which branches will be cut and citing Article 229.
Trim only up to the property line — avoid cutting into the trunk, main scaffold limbs, or more than 25% of the crown to prevent tree stress or death.
Dispose of trimmed branches properly; do not return them to the neighbor’s property unless agreed in advance.
If the neighbor objects or threatens legal action, consult a licensed bengoshi (attorney) or seek mediation via your municipal Chōchō Center.
