 ### Reaction timing
 
+:::warning
+
+The precise timing of reactive component activation is subject to change in the future as we optimize the implementation
+of reactive components. You should not rely on the exact timing of reactive components for complex effects.
+
+:::
+
 Reactive components responding to the change of a GameObject's active state will do so after a one frame delay. When the
 game object is being deactivated, the game object's deactivation will be delayed by one frame to happen at the same
 time.

 ### 反応タイミング
 
+:::warning
+
+リアクティブコンポーネントの反応タイミングは、実装を最適化するに連れて微妙に変更される可能性があります。精密なタイミング合わせを要求するギミックには
+リアクティブコンポーネントの反応タイミングに依存しないでください。
+
+:::
+
 GameObjectのアクティブ状態の変更に反応するリアクティブコンポーネントは、1フレームの遅延後に反応します。ゲームオブジェクトが非アクティブになる場合、
 ゲームオブジェクトの非アクティブ化は1フレーム遅れて行われ、同時に行われます。この理由については[Shape Changer](./shape-changer.md)
