NSA Trailing/Disaster/HRD Training

2025年6月8日（日曜日）Trailing/Disaster/HRD 訓練会を開催しました。AM6:00 本社資材置き場に集合しTrailing unitは、市街地で各unitの課題に対しての基礎訓練とステップアップの設定訓練を行いました。HRD unitは、土砂災害を想定したエリアや車両捜索とTFRの強化トレーニングを行い各ペアの改善点などを確認しながら次のステップに向けての訓練に臨みました。Disaster unitは、資材置き場内で、いくつかの設定で捜索精度の向上に努めました。
On Sunday, June 8, 2025, we held a Trailing / Disaster / HRD training session. The teams assembled at 6:00 AM at the headquarters materials yard.
The Trailing unit conducted both foundational training and step-up scenarios in an urban environment, focusing on each team’s current challenges.
The HRD unit carried out intensive TFR training and search exercises in areas simulating landslide conditions as well as vehicle searches. Each team worked on identifying areas for improvement and took steps toward their next training goals.
The Disaster unit focused on enhancing search accuracy through various scenarios set up within the materials yard.

Trailing training

モチベーションラン

モチベーションランでは、ヘルパーやコースなどを変更し臭跡に対して正しく認識できているのかどうか？なども確認しながら、単なる意欲の引き出しに留まらずに次のステップへのセッションを行った。
During the motivation runs, we varied the helpers and course layouts to assess whether the dogs were correctly recognizing the scent trail. These sessions went beyond simply boosting motivation—they also served as a transition toward the next level of training.

セントアーティクル トレーニング

セントアーティクルトレーニングでは、気温20℃・曇り時々小雨・湿度約70％・微風・トレール距離約300m・2屈折・15分経過の設定で2unitが取り組んだ。
In the scent article training, two units worked under the following conditions: temperature of 20°C, cloudy with occasional light rain, approximately 70% humidity, light breeze, a trail length of about 300 meters, two turns, and a 15-minute aging time.

幹線道路から住宅街を通過。途中に小さな交差点やわき道などが存在し、下り坂のコースである。一部坂道の途中はガードレール部分があり、臭跡が拡散しやすい区間も含まれている。
The course led from a main road through a residential area, including small intersections and side streets along the way. It followed a downhill path, with a section featuring a guardrail partway down the slope—an area where scent tends to disperse more easily.

車両・自転車・犬の散歩・畑仕事をしている人・通行人・誘惑臭などのディストラクションの中、犬の正しい反応の見極めは多くの設定の訓練を経験する必要がある。
In the presence of various distractions such as vehicles, bicycles, dogs being walked, people working in nearby fields, pedestrians, and tempting scents, accurately interpreting the dog’s response requires extensive experience with a wide range of training scenarios.

それぞれのunitのトレールは疑似しているが、交差点・わき道などでのネガティブの反応や、ハンドラーの読みとハンドリングに今後の課題が感じられました。
While the trails for each unit were similar in design, differences emerged in the dogs’ negative responses at intersections and side streets, as well as in the handlers’ ability to read these reactions and respond appropriately. These aspects revealed areas for future improvement in both interpretation and handling.

HRD training

気温が上昇し、湿度も高く捜索時間が長くなる事で精度の低下も考えられましたので、訓練開始のAM6:00前に、捜索設定エリアに原臭を5㎝程度の深さに設置し、約2時間後に各unitごとに捜索を開始した。環境状況の概略は、気温24℃・曇り・湿度約70％・南東の風約1m。
As the temperature rose and humidity remained high, extended search times posed a risk of reduced accuracy. To address this, the target scent was buried approximately 5 cm deep in the designated search area before the training began at 6:00 AM. Each unit then began its search approximately two hours later. The general environmental conditions were: temperature 24°C, cloudy skies, humidity around 70%, and a southeast wind at approximately 1 meter per second.

土砂災害想定

捜索開始地点は、ホットポイントの風上側からの上り勾配だった為にハンドラーが、ホットポイントの風下側へハンドリングするか？犬の走破性を活用して捜索エリアを自由捜索させ風下側のセントコーンを捉えさせるか？がポイントとなる。
Since the search starting point was on an uphill slope from the upwind side of the hot point, a key consideration was whether the handler should guide the dog downwind toward the hot point, or allow the dog to conduct a free search using its mobility to catch the scent cone from the downwind side.

全てのunitが、ホットポイントの3m付近から鼻の位置・動く速度に変化が表れ、セントコーンを捉えたことが明確なボディーランゲージで確認できた。課題は、TFRへの移行速度やスクラッチ行動の改善である。捜索現場によっては、TFRの姿勢が維持できな場所もある為に、TFRだけに拘らずに犬が明確なピンポイントの反応を示せるかどうか？が重要。スクラッチ行動は、基礎訓練から丁寧に取り組んで速やかに改善をしていく必要がある。
All units showed a noticeable change in nose position and movement speed within approximately 3 meters of the hot point, clearly indicating through body language that the scent cone had been detected. The key areas for improvement are the transition speed into the TFR and the refinement of scratching behavior. In actual search environments, maintaining the TFR posture may not always be possible. Therefore, rather than focusing solely on the TFR itself, it is crucial to ensure that the dog can give a clear and pinpoint response. Scratching behavior needs to be addressed carefully and systematically, starting from foundational training, to achieve prompt improvement.

車両検索

車両検索は、現段階では原臭の大きさに限界がある為に密閉状態ではなくドアの隙間を作りながら、3台の車両を検索し、ゼロ回答を含めた捜索設定となった。
At this stage, due to limitations in the size of the target scent, the vehicle search was conducted with slight openings left in the car doors rather than in fully sealed conditions. The training involved searches across three vehicles, including scenarios that required the dogs to give a zero response.

unit後それぞれに特徴が見られたが、原臭のポイントには、全てのunitが等しく反応を見せていた。
Each unit displayed its own distinct characteristics, but all units consistently showed a clear response at the target scent location.

Disaster training

今回は、要救助者が障害物に遮断されている状況下でのピンポイントアラートの訓練を設定し、建物の中と車両の中の要救助者の捜索訓練を行った。
This time, training was designed to focus on pinpoint alerts in scenarios where the victim was obstructed by barriers. Search exercises were conducted for victims located inside a building and inside a vehicle.

遮断されている状況下では、ボディーランゲージは見せるものの、自信を持ってバークアラートできない場面もありましたので、繰り返し自信のある捜索ができるように今後も強化が必要。
In obstructed scenarios, although the dogs did display body language indicating scent detection, there were instances where they were unable to confidently give a bark alert. Ongoing reinforcement is necessary to build their confidence through repeated successful search experiences.

車両内の要救助者に対しての意識が、中々確認できない時間が続き、紐付きでの捜索も含めて経験を積む事ができました。
There were extended periods during which the dogs had difficulty showing clear awareness of the victim inside the vehicle. However, this provided valuable training opportunities, including on-lead searches, allowing the teams to gain important experience.

NSAの活動は、民間ボランティアによる活動です。
多くの方々からご支援いただくことで、より速く、より多くの行方不明者捜索にサーチドッグを派遣することができます。皆様のご支援をお願いいたします。
NSA’s activities are carried out by civilian volunteers.
With the support of many individuals, we can deploy search dogs more quickly and to a greater number of missing person cases.
We sincerely ask for your continued support.
