Yamanakako Tourist Information Office: September 23 Holiday Opening and Weekly Hours

Travel News Watch

Information checked: September 22, 2026 at 8:40 AM JST.

The Yamanakako Tourism Association posted a fresh reminder on September 20 about the main village tourist information office’s weekly closure and revised hours. The timing matters for Silver Week visitors because Wednesday, September 23 is a national holiday and therefore falls under the office’s stated holiday-opening exception.

Short answerThe main Yamanakako tourist information office is normally closed every Wednesday, but it opens when Wednesday is a public holiday. September 23, 2026 is Autumnal Equinox Day, so the office is scheduled to open under that exception. Its current hours are 8:30 AM-5:15 PM. The Hirano Tourist Information Office has separate hours of 9:30 AM-5:30 PM and remains available on regular Wednesdays.

What Changes For September 23

September 23 falls on a Wednesday in 2026, but it is also Autumnal Equinox Day. Japan’s Cabinet Office lists it as a national holiday, and the Yamanakako Tourism Association states that the main information office opens when its usual Wednesday closure falls on a public holiday.

Visitors can therefore plan to use the main office on September 23 during the published 8:30 AM-5:15 PM hours. Because same-day staffing or emergency changes can still occur, call the tourism association before making a special cross-lake trip solely for counter service.

The Regular Weekly Pattern

Outside public-holiday exceptions, the main Yamanakako tourist information office closes every Wednesday. Its current published hours are 8:30 AM-5:15 PM, changed from the former 9:00 AM-5:30 PM schedule in April 2026.

Travelers should not assume that all information counters around the lake follow the same schedule. The Hirano Tourist Information Office is listed as open when the main office takes its regular Wednesday closure, and its published hours are 9:30 AM-5:30 PM.

When The Information Office Is Useful

An in-person counter can help with local maps, current sightseeing ideas and orientation when online information is unclear. It is especially useful for travelers adjusting a lakeside itinerary after weather changes or deciding which part of the lake to visit next.

For transport timetables, attraction opening status or weather-sensitive activities, confirm directly with the relevant operator as well. The tourism office schedule does not guarantee that every bus, boat, museum or outdoor facility follows the same holiday hours.
