The 1995 Tokyo subway sarin attack enters the narrative as a later event that changed security across Tokyo. Its significance here is the contrast between the relatively open access Jake Adelstein encountered at the Tokyo Metropolitan Police Department and the stricter procedures that followed the attack.

Chronology and Context

During Adelstein’s visit, a police escort was technically required for visitors who were not registered members of the press club, police employees, or people with security clearance. An exception was made for Ansei Inoue, who came and went as he pleased. The account places the attack three years after this visit, marking the earlier access arrangements as a pre-attack condition.

Security Consequences

The attack had the effect of tightening security procedures across the city. The account does not specify the measures introduced; it identifies the attack as the turning point after which the earlier, looser conditions no longer applied.

Narrative Significance

Rather than recounting the attack itself, the narrative invokes it to explain a change in the institutional atmosphere surrounding access to the police. The brief reference makes a later event a dividing line: ordinary movement through the Tokyo Metropolitan Police Department had been possible for some visitors before the attack, while security tightened afterward.
