Yakuza Accused of Clearing a Hiroshima Forest to Build an Illegal Road

A road can take control of land without moving the land itself. Fell the trees, cut the slope and compact a surface wide enough for machinery, and the legal title may remain unchanged while control on the ground shifts. That distinction explains why police in Hiroshima are treating the alleged creation of a mountain work road as something more than unauthorized logging.

According to local reports citing Hiroshima Prefectural Police, officers on July 14 arrested Shingo Kawashita, 42, the head of the Harada-gumi, and four other members on suspicion of real-estate encroachment. The Harada-gumi is affiliated with the Kyosei-kai, a Hiroshima-based organization designated under Japan’s anti-organized-crime law. Police suspect the five acted with several other people to cut trees and create a work road with heavy equipment on privately owned woodland in Minami-Okocho, Minami Ward, from April 2025 for roughly one year.

The following day, police searched the Kyosei-kai headquarters with about 120 investigators and examined the adjacent mountainside. Aerial images showed several road-like cuts extending through the hill behind the headquarters toward a public road ascending Mount Ogonzan. Local television reported that approximately 3,000 square meters had been cleared. The inquiry began after an officer saw a truck carrying what appeared to be felled timber in April 2025; the landowner reportedly said they knew nothing about the work.

Those are allegations at an investigative stage. Police have not disclosed how the five responded to them. The purpose of the road remains unknown. No public evidence yet establishes that the Kyosei-kai headquarters or senior figures ordered or approved the work. An arrest is not a conviction, and the scale of a search cannot substitute for proof of any individual’s criminal responsibility.

What is known, what police allege—and what remains open

The 1960 law that made it possible to “steal” real estate

Article 235-2 of Japan’s Penal Code provides that a person who encroaches upon another person’s real property is punishable by imprisonment for up to 10 years. The provision contains no alternative fine. It is often described as the real-estate counterpart to theft, but land cannot be carried away. The legal focus is therefore a transfer of possession: conduct sufficiently substantial to exclude another person’s factual control and place the property under the offender’s or a third party’s control.

Not every unauthorized step onto another person’s land qualifies. A brief trespass may raise a different question. Courts assess the character and duration of the conduct, the area affected, physical barriers or structures, the way the property was used and the degree to which the prior possessor’s control was displaced. Fencing land, placing a building, maintaining exclusive use or materially reshaping a site into a usable road can be evidence of the required change in control. Hiroshima University law professor Nobuto Yoshinaka told local television that the offense concerns occupying real property against the rights holder’s will.

The offense was not part of Japan’s original 1907 Penal Code. The Diet inserted it immediately after the theft article through Law No. 83 of May 16, 1960, effective 20 days after promulgation. The reform addressed a gap exposed by postwar cases in which buildings or land could be taken through occupation and faits accomplis but did not fit comfortably within theft’s traditional focus on movable property. The same law created a separate offense for destroying, moving or removing boundary markers so that a land boundary can no longer be recognized.

In Hiroshima, investigators are concerned not only with the value of timber but with the alleged transformation of the mountain into a route that could be used over time. The felled trees, damaged slope and owner’s losses may create other legal and civil questions. The arrest allegation, however, centers on interference with control of the real property itself.

Three thousand square meters and the Forest Act: one number is not a verdict

An “illegal road” through woodland naturally raises questions under the Forest Act. Yet Japan’s development-permission rules depend on the forest’s legal classification, the purpose of the work, its total area and the road width. They are a separate layer from the owner’s consent. The Forestry Agency and Hiroshima Prefecture say that in privately owned forest covered by a regional forest plan, work devoted exclusively to a new or altered road generally requires prefectural development permission when the affected area exceeds one hectare and the road’s ordinary width exceeds three meters. The general threshold for other development is also more than one hectare; for solar facilities, it is more than 0.5 hectare.

The reported 3,000 square meters equals 0.3 hectare—below the national one-hectare threshold on its face. That does not mean development is freely permitted. First, a person needs authority to use another owner’s land and cut another owner’s trees. Second, if the site is private forest under a regional forest plan, Article 10-8 establishes a logging-and-reforestation notification system. A forest owner or holder of the relevant tree rights generally files with the municipality between 90 and 30 days before cutting, followed by reports after logging and reforestation. Protected forest is subject to stricter approval or notification.

Depending on the exact site and work, urban planning, land development, sediment control, road connection, drainage, soil disposal, cultural-property or municipal rules can add further requirements. The public record does not yet establish whether this parcel is in a regional forest plan, whether it is protected forest, the road width or volume of cut and fill, or what administrative papers were or were not filed. It would therefore be premature to declare either that a Forest Act violation occurred or that none could apply.

A mountain road is not a line—it is an alteration of water and soil

On a map, a work road is a line. On a mountain, it is a collection of cut slopes, embankments, shoulders, drainage points, turning spaces and cleared strips. Forestry-road guidance emphasizes routes that follow terrain, minimize cut and fill, disperse surface water and prevent erosion where necessary. That is because a road changes the movement of rain. If it collects runoff and releases it at one point, it can scour topsoil and destabilize a slope.

Hiroshima has acute experience of slope disaster. In August 2014, torrential rain triggered debris flows and slope failures across the city, killing 77 people, including three disaster-related deaths. No public evidence says the road in the present case has caused a slide or faces the same conditions. The historical disaster nevertheless explains why a cut into an urban mountainside demands questions about drainage and stability as well as property rights.

Restoration is not as simple as planting seedlings. Specialists may need to decide how to treat a compacted surface, stabilize cut and fill, distribute rainwater, restore topsoil and monitor vegetation. Removing the road too aggressively could disturb the slope again; leaving it could preserve an unauthorized drainage path. For the owner, losses may include not only the timber but surveys, engineering, construction and long-term maintenance.

Kyosei-kai: a Hiroshima organization formed from seven groups in 1964

“Yakuza” is the familiar historical and popular term. Japanese law uses boryokudan, commonly translated as organized crime group or crime syndicate. The Anti-Boryokudan Act defines such a group by the risk that its organization encourages members to commit violent illegal acts collectively or habitually. A prefectural public safety commission may designate a group that meets statutory criteria. Designation does not make every act by every member criminal; it provides administrative controls over specified demands, recruitment, obstruction of departures and conduct during conflicts.

The official history of the Kyosei-kai leads directly into postwar Hiroshima. The National Police Agency’s 1993 white paper said the then-fourth-generation Kyosei-kai originated in the “Political Association Kyosei-kai,” formed in May 1964 when Tatsuo Yamamura, head of the Yamamura-gumi and described as a gambler, brought seven groups together. At the time of designation, the white paper recorded about 330 members and a sphere of influence within Hiroshima Prefecture.

Its prehistory lay in the unsettled postwar economy: black markets, ports, entertainment, gambling, competition among local groups and expansion by national syndicates in the 1960s. The conflicts were not cinematic folklore. They involved shootings and risks to people outside the organizations. The same white paper recorded a 1988 incident in which a Kyosei-kai member fired a handgun inside the Hiroshima Shinkansen station and a stray bullet injured a civilian.

Kinji Fukasaku’s 1973 film Battles Without Honor and Humanity and its sequels transformed the postwar Hiroshima gang wars into national cultural memory. The films are dramatized works, not primary historical records. Their rough energy can become an obstacle to understanding when it obscures victims, fear, revenue extraction and the cost imposed on communities.

From gamblers and street vendors to corporate fronts

Modern yakuza mythology traces parts of its identity to Edo-period bakuto, operators of illegal gambling, and tekiya, organizers of itinerant stalls at festivals and markets. Patron-client ties, sake rituals, territory and mediation are often connected to these worlds. But presenting contemporary syndicates as the unbroken heirs of romantic chivalry is misleading. Modern policing, urbanization, the wartime and postwar economy, construction, entertainment, stimulant drugs and corporate extortion repeatedly transformed the organizations.

Groups expanded through black markets, port labor, entertainment and gambling after 1945. During the high-growth decades, national expansion and violent disputes intensified. Police launched concentrated “summit operations” against senior leadership in the 1960s, but organizations adapted through dissolution and reorganization, name changes and legitimate-looking businesses. Activities moved into the borderlands between lawful transactions and coercive power: land assembly, debt collection, corporate racketeering, construction, waste, nightlife and finance.

The 1993 police white paper described “civil-intervention violence”—using the appearance of a private transaction to enter disputes over debt, accidents or land—and the growing use of front companies that concealed organized-crime control or support. Land, construction and waste have historically attracted scrutiny because physical access, complicated ownership, subcontracting chains, cash, permits and local intimidation can converge.

That general history is not evidence of the motive in this case. The public does not know whether the timber had a commercial purpose, whether the road was intended to reach a future facility or vehicles, or whether anyone sought to create a fait accompli over land use. History identifies questions for investigators; it cannot answer them in place of evidence.

The 1992 break: the Anti-Boryokudan Act and exclusion from ordinary commerce

Japan enacted the Anti-Boryokudan Act in 1991 and brought it into force on March 1, 1992. In addition to prosecuting offenses under ordinary criminal law, the act allowed authorities to issue stop orders against specified coercive demands—such as protection payments made while invoking the power of a designated group—and to regulate forced recruitment and obstruction of members who sought to leave. The Kyosei-kai was designated under this system and appeared in detail in the following year’s national police white paper.

Organized-crime exclusion ordinances later spread through every prefecture. Businesses added anti-social-force clauses to contracts, while access to bank accounts, rental housing, insurance, phones, public works and other parts of the legitimate economy narrowed. Civil suits pursued senior leaders under theories of representative or employer responsibility, and amendments expanded leadership liability and support for injunctions against offices.

The numbers show dramatic contraction. The National Police Agency reports that the combined number of members and associates was 91,000 when the law was enacted in 1991. At the end of 2025 it stood at a record-low 17,600: about 9,400 members and 8,200 associates and other connected persons. Arrests of members and associates also fell to a record-low 7,335.

Contraction is not disappearance. Police warn that some groups obscure their activities and diversify revenue. Members and former members have been found connected to “anonymous and fluid crime groups,” which recruit disposable actors online for fraud, robbery and theft. Japan now confronts links between hierarchical organizations that historically displayed names and offices and networks whose personnel and identities continually change. The Hiroshima road is strikingly physical by comparison. A cut left in a hillside cannot be erased by shutting down an account or server.

What a 120-investigator search is designed to find

A large headquarters search can pursue several evidentiary chains: who ordered the work; when; who paid; how machinery, fuel and surveys were obtained; where the timber went; what messages, maps or land records exist; and how the road was intended to be used. Investigators need to distinguish personal conduct from action on behalf of the Harada-gumi and, separately, determine whether anyone at the Kyosei-kai headquarters knew of or directed it. They must also measure the physical alteration to show the degree of alleged “encroachment.”

Organized-crime investigations cannot stop at identifying labor on the ground. They seek decision-makers, intended beneficiaries and money flows. But a group’s hierarchy does not itself prove conspiracy by higher figures. Prosecutors still need evidence of direction, reporting, funding or shared purpose.

A search warrant is issued after a judge reviews the need and objects of the proposed search. It does not declare everyone at the searched premises guilty. Neither designation nor membership removes the right to silence, legal defense or the presumption of innocence. Strong enforcement against organized crime and evidence-based limits on individual responsibility must coexist.

The work left for the owner and the community

The mountain will not restore itself when the criminal case ends. The owner may consider civil claims for trees, lost use, slope damage, surveys, design and repair. Authorities must examine logging and development procedures, protected-area status, drainage and safety. A criminal sentence and responsibility for making land safe are separate questions.

The most difficult issue may be defining “original condition.” Mature trees cannot be replaced on a court timetable. Excavating a compacted road can disturb the slope again; leaving it can preserve an unauthorized route and drainage pattern. Geotechnical and forestry specialists may need to inspect soil, water and vegetation, then design staged restoration and monitoring.

Across Japan, some forest parcels are owned by older people, inherited through unresolved estates, held by people living far away or marked by uncertain boundaries and light day-to-day management. Nothing public establishes that those circumstances apply to this owner. The broader lesson remains: an owner’s physical absence cannot become an opening for third parties to create facts on the ground. Land registration, forest records, logging notices, aerial observation and local reports need to function as one system.

Nine facts to watch next

Conclusion: a shrinking organization, a road that remains

The Hiroshima case is neither a spectacular gang conflict nor an anonymous cybercrime. It concerns an allegation of physical control in its most traditional form: machinery brought down trees, moved soil and cut a route across someone else’s mountain. Investigators reached for a Penal Code provision created in 1960 to punish the effective seizure of land without carrying it away.

Nearby stands the headquarters of a group whose official history begins with seven organizations brought together in Hiroshima in 1964, and which has since passed through the Anti-Boryokudan Act and decades of social exclusion. Even after the national population of members and associates fell from 91,000 in 1991 to 17,600 in 2025, organized crime cannot be measured by headcount alone. What matters is how coercive organizations connect to land, companies, anonymous networks and community silence.

Two shortcuts must be resisted. One is to decide the guilt of the arrested men or senior organizations from affiliation alone. The other is to dismiss the alteration because 0.3 hectare is below the general national threshold for forest development permission. Ownership, possession, logging procedure, slope safety and restoration are distinct legal and factual questions.

The road under the moonlight does not yet reveal why it was built. It shows only that trees are gone, the terrain has changed and the owner reportedly did not know. The next steps are for police to establish purpose and direction with evidence, for administrators to clarify forest status and safety, for courts to assess individual responsibility, and for someone ultimately to repair the mountain.
