向島百花園
The last Edo townspeople’s garden, lit for three moon nights
Kigo · 尾花 · obana · autumn
The frail silver grass stirs in the autumn wind — yet beneath the moon, the deepening night lies clear and still.
Emperor Kōgon · 14th century
Moon-viewing follows named nights of the old lunar calendar, not a season. In 2026 the harvest moon, Chushu no Meigetsu, is on 25 September and the second viewing night, Jusanya, on 23 October. The named night and the astronomical full moon need not match: this year the full moon comes two days later, at 01:49 on 27 September.
How long it lastsOne evening each, though organisers often add a night or two: Daikaku-ji's evenings run 25–27 September 2026. Cloud or rain can end it, and the temple decides at 11:00 each day whether the boats go out.

If you are earlyThe named night cannot be moved by travelling north or uphill. Another clear evening shows much the same moon, by the local moonrise table, but it is not Chushu.
If you are lateJusanya, 23 October in 2026, is a second viewing night with its own customs, not a repeat of the first.
