Tokyo Stock Exchange morning and afternoon trading blocks

At 9:00 JST the morning block opens. It closes at 11:30. Lunch runs 11:30 to 12:30. The afternoon block starts at 12:30 and ends at 15:00 JST. That is the full trading day.

  • Morning block: 9:00-11:30 JST
  • Afternoon block: 12:30-15:00 JST

Both blocks are fixed year-round. Japan does not observe daylight saving time, so these hours do not shift between summer and winter.

Does the Tokyo Stock Exchange have a pre-open and closing auction?

Yes. Before the main block opens, the pre-market runs 8:00-9:00 JST. Orders can be entered and cancelled during this hour. The closing auction (itayose) happens at 15:00 JST, when the exchange executes final trades at a single price.

  • Pre-market: 8:00-9:00 JST
  • Closing auction: 15:00 JST

Forex overlap: Tokyo hours with Sydney and London

The Tokyo forex block overlaps with two other major centres.

  • Sydney: Australian markets open at 7:00 JST. On 15 July 2026 Sydney is 1 hour ahead of Yokohama. On 15 January 2026 it is 2 hours ahead. The overlap runs from 7:00 to 15:00 JST.
  • London: The London block opens at 16:00 JST. On 15 July 2026 London is 8 hours behind Yokohama. On 15 January 2026 it is 9 hours behind. The overlap runs from 16:00 to 23:00 JST for afternoon TSE traders who continue after 15:00.

How do Yokohama traders handle JST and maritime UTC?

Yokohama is a major port city. Local traders, shipping companies, and logistics firms operate on JST for local business. For maritime operations, they use Coordinated Universal Time (UTC). This dual system matters for cargo deadlines, customs filings, and vessel schedules.

A Yokohama-based trader placing an order with a counterpart in London at 14:00 JST needs to remember London is 8 to 9 hours behind, depending on the season. A shipping firm scheduling a container pickup from the Port of Yokohama uses JST for the local team but UTC for the vessel’s arrival time.
