How to Keep Records of Stalking | Keeping Incidents in Date Order

FactSort Lab.March 16, 2026Revised September 29, 2026

What a consultation desk asks

Suppose the intercom rang at 2:15 a.m., but no one appeared on the recording. When this is reported at a police consultation desk, the person may be asked, "Was there any actual harm?"

To understand the situation, the person receiving the consultation needs specific information: when, where, and what happened. An incident that is hard to assess on its own can be read as a course of events when several incidents are arranged in date order. How the police respond depends on the circumstances of each case.

Records written afterwards

In a frightening situation, it may not be possible to note the date, time, and place on the spot. When an incident is written down later from memory, adding the date of writing to the record shows when the record was made.

Dividing the incidents

Dividing incidents into contact during everyday movements and contact with the residence makes the course of events easier to follow. This division is for organizing only. Which category an incident falls into, and how it is assessed legally, is for the place of consultation to judge.

Contact during everyday movements

Contact with the residence and daily life

Incidents that fit neither category, or whose connection is unclear, can be recorded separately as "reference information." Mixing them with the main record makes the course of events harder to read.

Items to record for each incident

For each incident, the record contains the date and time, the place, what happened, and the materials that remain. Guesses about the other party's intentions are written separately from observed facts.

Date and timeWhen it happened. If the exact time is unknown, it is written as "around [date]" or "estimated around [time]," with the basis if there is one.
PlaceWhere it happened: the building entrance, inside the elevator, the exit of the nearest station, and so on.
What happenedThe observed facts, written as "I was ...," "I saw ...," "I heard ...."
MaterialsWhat remains: photos, screenshots, receipts, a diary, message history, with file names and dates.

Materials at hand

A convenience store receipt shows that the writer was at a particular store at 7:42 p.m. on January 22, 2024. It can serve as support for the date, time, and place of an incident. Materials at hand can be reviewed from the standpoint of whether they show when and where the writer was.

Examples of materials that can be used in the record

Security camera footage may be kept only for a limited period. One option is to ask the management company or the store early on whether the footage can be preserved.

What date order shows

Arranged in date order, changes in frequency and place become visible that were hard to see when each incident was looked at on its own. If contact that occurred once in December became two or three times a week from mid-January, and the place moved from the hallway and entrance to the mailbox, the intercom, and the doorknob, that course of events can be shown to the place of consultation.

Steps and an example of the output

  1. Write out the incidents that are remembered, from diaries, notes, lists of photos, and messages, in any order. They can be written in spoken language or as bullet points.
  2. Divide them into contact during everyday movements and contact with the residence. Incidents that fit neither are recorded separately as "reference information."
  3. Rearrange them by date and time, and check for changes in frequency, place, and content.

When records like these are entered into the organizing tool, it outputs a statement of facts and a chronology such as the following.

Example of the output (fictional case, excerpt; translated from Japanese)

1. Overview

The writer records stalking and contact with the residence by a man living in the same apartment building (the "subject"). The frequency of contact increased from January 2024, and late at night on February 1, the writer heard the doorknob being turned from outside.

2. Chronology (excerpt)

Date/timeTypeWhat happenedRecord
01/15 23:30ApproachThe subject was waiting at the building entrance and followed the writer in.Diary

01/22 19:45ApproachOn the way back from a convenience store, the subject followed about 50 m behind. The writer saw him waiting in the shadows.Receipt
02/01 23:50ResidenceThe writer heard the metallic sound of the front doorknob being turned from outside, twice. The door was locked, and no one entered.LINE

The actual output depends on what is entered. When AI organizes an account, content not in the original record may be added, and content that was written may be dropped. How often this happens is measured in the research reports.

Types of places that take consultations

Places that take consultations include the police, lawyers, and consultation desks run by local governments and others. Which one handles a matter depends on the situation.
