野村證券が隠蔽 「レイプ未遂事件」
顧客強盗放火後も「犯罪」は継続
2026年8月号公開
前代未聞の野村證券社員による強盗殺人未遂罪。梶原優星被告（31）の７月23日の控訴審判決で、広島高裁は懲役18年とした一審判決を支持し、弁護側の控訴を棄却した。富裕層への金融商品販売を担う「ウェルス・マネジメント（ＷＭ、リテール）部門」の社員が、顧客の現金を奪い自宅に火をつけるという言語道断の事件だった。
実は、この事件の裁判中に同じＷＭ部門で重大な不祥事が起きていた。だが、「これ以上の不祥事の発覚は避けたい」という経営陣の保身が働いたのか、揉み消しが図られ、事件は隠蔽された。
この不祥事を明らかにする前に、広島の事件を振り返っておこう。
野村證券広島支店でＷＭ部門に従事していた梶原被告は２０２４年７月22～24日の間、顧客である80代の高齢夫婦宅から現金約８００万円を盗んだ。さらに同月28日には夫婦宅で妻に睡眠作用のある薬物を服用させて昏睡状態にし、現金約１８００万円を盗み、放火して殺害しようとした。
20代後半の営業マンと、80代の高齢顧客という構図は野村を中心とした対面証券では珍しくない。孫のように懐に入り込み、信頼させた上で営業をかける―。対面証券の「流儀」が、最悪の形で事件化してしまった。
24年12月には奥田健太郎社長らが会見を開き、「お客様の大切なご資産をお預かりしている金融機関として絶対にあってはならない事態であり、大変重く受け止めている」と謝罪。「私自身が先頭に立って信頼回復に努めていく」と誓った。
同社は再発防止策として、顧客宅に訪問する際には上席管理者の「事前承認」を得る、訪問の前後に管理者が顧客と電話するなどを打ち出した。さらに社員の監視強化の一環としてＧＰＳ機能で位置情報がわかるアプリの導入も義務づけた。
初公判が広島地裁で開かれた今年２月には、ＷＭ部門の全社員に自身の借金の残高や返済状況などがわかる信用情報の提出を求めてもいる。社内は「謹慎ムード」に包まれ、社員らの飲み会は上席管理者への許可制となった。
エース社員が犯した性加害
そんな最中、ＷＭ部門の「プライべート・ウェルス・マネジメント（ＰＷＭ）部」の社員らが大規模なゴルフコンペを秘密裏に開催していたことが小誌の取材で発覚した。
ＰＷＭ部は、野村の屋台骨であるＷＭ部門のなかでも、上場企業や大手未上場企業のオーナー、経営者などの超富裕層に特化し、資産運用や税務、相続など包括的なコンサルティングを行う専門部署だ。ソフトバンクグループの孫正義やＺＯＺＯ創業者の前澤友作ら大物創業者もクライアントとされ、他社証券も羨む野村の「心臓部」だ。
ＰＷＭ部のメンバーは野村きっての精鋭部隊であり、「自分たちは別格」との驕りがあったのかもしれない。野村グループが運営する埼玉県の「こだまゴルフクラブ」で、ＰＷＭ部を担当する栗原裕治常務（当時）らが主催し、参加者が１００人を超える大規模なコンペとなった。
栗原は、24年12月に奥田社長とともに会見で謝罪した営業部門トップの杉山剛専務（当時）の「懐刀」。同社関係者は「ＷＭ部門の元社員が殺人未遂事件で裁判中だというのに、お祭り騒ぎをする神経が疑われる。社内ではＰＷＭ部への不信感が高まっている」と話す。
だが、真の問題はここからだった。前出の関係者が明かす。
「帰りの車中で男性社員が、女性社員の胸を無理やり揉んだり、キスを迫ったりレイプ未遂に及んだというのです。この人物は、従業員組合委員長も務めた人物で将来の役員候補でした」
組合委員長ポストは、同社の永井浩二会長も務めた出世コース。そんなエースの不祥事にＰＷＭ部には激震が走った。外部に漏れれば、「私自身が先頭に立って信頼回復に努める」と宣言した奥田の責任問題となろう。社内では保秘が厳命され、揉み消し工作が図られたという。
レイプ未遂の当人は資産管理コンサル会社に転職し、取締役に就任。解雇処分だったというが、転職先のホームページでこの人物は野村證券でＷＭ業務に従事した経歴をアピールしている。
小誌は野村證券に対し「レイプ未遂事件」について事実関係を問うたところ「個別の社員に関する問い合わせについては回答を差し控える」と木で鼻をくくった対応。
ただ、「なお当社では、社員による不適切行為の疑いを把握した場合には、速やかに必要な事実確認を行い、法令および社内規程に基づき、経営層への報告・関与のもと、厳正かつ適切に対応している」と、奥田ら経営陣に事件が共有されていることを示唆するかのような回答も付け加えている。
責任者はこっそり「左遷」
今年４月の人事ではＷＭ部門で人事刷新があったが、実はこの事件が影響したというのがＰＷＭ部内のもっぱらの見方だ。
まず、部門トップの杉山は親会社の野村ホールディングス（ＨＤ）執行役副社長に転じた。昇進とも言えるが、野村信託銀行の社長との兼務。同行は社員６００人ほどの小所帯であり、ＨＤ社長候補の一人でもあった杉山のポストとしては、実質的な左遷であるとの見方が強い。
「レイプ未遂ゴルフコンペ」開催の「主犯格」である栗原は、野村不動産ホールディングスの執行役員という明らかな左遷人事となった。新たなＰＷＭ担当はコンペ時に担当外だった竹田賢司常務が就任した。
奥田体制は今年で７年目。前任の永井の社長任期が８年だったため、奥田は早ければ来春にも交代するとの観測も出ている。海外のインベストメント・バンキング部門出身の奥田はもともとリテール部門に冷淡であるとされており、「これでＷＭ部門からのトップ選出はなくなった」との見方が出ている。
そんな奥田が主導する形で野村證券は近年、「脱どぶ板営業・ノルマ型営業」を掲げ、取引ごとに手数料を稼ぐフロー型ビジネスから、顧客の残高に応じて収益を得るストック型ビジネスへの転換を推進している。
収益の安定化と言えば聞こえがよいが、どんなに市況が悪いときでも顧客の資産から変わらずにお金を抜き続けることを意味する。これが成功するには、顧客から納得感を得られる、高度なコンサルティング能力や高い倫理観が不可欠だ。不祥事が相次ぐＷＭ部門の社員が現状ストックビジネスに値する水準にあるのか。経営陣には胸に手を当てて考えてもらいたい。（敬称略）
Nomura Securities Covered Up an "Attempted Rape Incident" — The "Crimes" Continued Even After the Robbery and Arson Against a Client
An unprecedented case: attempted robbery-murder by a Nomura Securities employee. In the July 23 appellate ruling for defendant Yusei Kajiwara (31), the Hiroshima High Court upheld the district court's 18-year prison sentence, rejecting the defense's appeal. It was an unspeakable crime committed by an employee of the Wealth Management (WM/Retail) division, which handles the sale of financial products to wealthy clients — he robbed a client of cash and set fire to their home.
In fact, while this case was on trial, another serious scandal was unfolding within the same WM division. But apparently driven by executives' self-preservation instinct — a desire to avoid the exposure of yet another scandal — the matter was hushed up and covered up.
Before revealing this scandal, let's first review the Hiroshima incident.
Kajiwara, who worked in the WM division at Nomura Securities' Hiroshima branch, stole roughly 8 million yen in cash from the home of an elderly couple in their 80s who were his clients, between July 22 and 24, 2024. Then, on the 28th of the same month, he drugged the wife with a sleep-inducing substance to render her unconscious, stole approximately 18 million yen in cash, and set the house on fire in an attempt to kill her.
The pairing of a salesman in his late twenties with an elderly client in his or her 80s is not unusual at face-to-face brokerages centered around firms like Nomura — working one's way into a client's confidence like a grandchild before making a sales pitch. This "tradition" of face-to-face brokerage sales culminated in the worst possible way.
In December 2024, President Kentaro Okuda and others held a press conference to apologize, stating that as a financial institution entrusted with clients' important assets, this was a situation that should never happen under any circumstances, and that they took it extremely seriously. He vowed to personally take the lead in restoring trust.
As a preventive measure, the company introduced rules requiring prior approval from a senior manager before visiting a client's home, along with phone calls to clients by managers before and after such visits. It also mandated the introduction of a GPS-tracking app as part of stepped-up employee monitoring.
At the first hearing at the Hiroshima District Court this past February, the company also required all WM division employees to submit credit information disclosing their debt balances and repayment status. The office was enveloped in a mood of self-restraint, and employee drinking parties required approval from senior managers.
A "Star Employee" Committed a Sexual Assault
Amid all this, this magazine's own reporting uncovered that employees of the WM division's Private Wealth Management (PWM) department had secretly held a large-scale golf outing.
The PWM department is a specialized unit within Nomura's core WM division, focused on ultra-wealthy clients such as owners and executives of listed and major unlisted companies, providing comprehensive consulting on asset management, taxation, and inheritance. Its clients reportedly include major entrepreneurs such as SoftBank Group's Masayoshi Son and ZOZO founder Yusaku Maezawa — it is the "heart" of Nomura, envied by rival brokerages.
PWM members are considered Nomura's elite corps, and there may have been an arrogance among them — a sense that "we're on another level." The large golf outing, with over 100 participants, was hosted at "Kodama Golf Club" in Saitama Prefecture, operated by the Nomura Group, and organized by then-Managing Director Yuji Kurihara, who was in charge of the PWM department.
Kurihara was the right-hand man of then-Senior Managing Director Tsuyoshi Sugiyama, the head of the sales division who apologized alongside President Okuda at the December 2024 press conference. A source at the company said that given a former WM division employee was on trial for attempted murder, holding a festive celebration showed questionable judgment, and that distrust toward the PWM department was growing internally.
But the real problem lay elsewhere, the same source revealed: on the ride home, a male employee allegedly forced himself on a female employee — groping her breasts, trying to force a kiss, and going as far as attempted rape. This individual had served as chairman of the company's employee union and was considered a future candidate for the board.
The union chairman position is a career track that has historically led to advancement — Chairman Koji Nagai himself once held the post. The scandal involving this rising star sent shockwaves through the PWM department. If it leaked externally, it would become a matter of accountability for Okuda, who had declared he would personally lead efforts to restore trust. Internally, strict confidentiality was ordered, and a cover-up was reportedly orchestrated.
The man at the center of the attempted rape allegation moved to an asset management consulting firm and was appointed as a director there. He was reportedly dismissed from Nomura, but on his new employer's website, he touts his background working in WM operations at Nomura Securities.
When this magazine asked Nomura Securities about the facts surrounding the "attempted rape incident," the company gave a curt, evasive response, stating that it would refrain from commenting on inquiries regarding individual employees.
However, the company added a statement that seemed to suggest the matter had indeed been shared with Okuda and other executives: "When we become aware of suspected inappropriate conduct by an employee, we promptly conduct the necessary fact-finding and respond strictly and appropriately based on laws and internal regulations, with reporting to and involvement of management."
The Person Responsible Was Quietly "Demoted"
There was a personnel reshuffle within the WM division this past April, and the prevailing view within the PWM department is that this incident actually influenced those changes.
First, division head Sugiyama moved to become an Executive Vice President at parent company Nomura Holdings (HD) — nominally a promotion, but combined with the role of president of Nomura Trust and Banking. Since that bank has only about 600 employees, the prevailing view is that this was effectively a demotion for Sugiyama, who had been considered one of the candidates for HD president.
Kurihara, described as the "ringleader" behind organizing the "attempted-rape golf outing," was moved to executive officer at Nomura Real Estate Holdings — a clear demotion. Managing Director Kenji Takeda, who had not been involved in the outing, was appointed as the new head of PWM.
This is the seventh year of the Okuda administration. Since his predecessor Nagai served eight years as president, there is speculation that Okuda could be replaced as early as next spring. Okuda, who came up through the overseas investment banking division, is said to have originally been cool toward the retail division, and the view has emerged that this effectively rules out any future top leadership coming from the WM division.
Under Okuda's leadership, Nomura Securities has in recent years championed a shift away from door-to-door, quota-driven sales, moving from a flow-based business model earning fees per transaction toward a stock-based model earning revenue based on client asset balances.
Framed as revenue stabilization, this sounds appealing, but it essentially means continuing to draw money from client assets regardless of how poor market conditions may be. For this to succeed, advanced consulting ability and a high standard of ethics — the kind that earns genuine client trust — are indispensable. Whether WM division employees, amid a string of scandals, currently meet the standard required for a stock-based business model is a question management should honestly reflect on.
