Listeners planning to travel to Japan in late September 2025 can expect pleasant, cooler weather and fewer tourist crowds as the country transitions from summer into autumn. This period is ideal for exploring cities, gardens, and nature spots at a relaxed pace, with seasonal customs like Tsukimi, the moon-viewing festival, adding local charm, according to HireTaxiJapan. Shrines and gardens such as Kyoto’s Kiyomizu-dera and Nanzen-ji can be enjoyed without the heavy traffic of later fall, and Nikko, north of Tokyo, begins to show hints of autumn color, while places like the Norikura Highlands and Hakone offer tranquil outdoor experiences and events like the harvest moon over Mount Fuji.

However, listeners should be aware that **September falls within Japan’s typhoon season**, typically active from mid-June through early October. As highlighted in travel tips by content creators and Japan specialists, while major typhoons are infrequent, even milder storms can lead to flight delays, cancellations, and disrupted train services—especially in regions like Nagano and Kyushu, which have experienced severe flooding in past years. If traveling during this period, it’s wise to build extra buffer days into your itinerary to account for possible transportation interruptions and to stay updated with weather advisories.

For those flying to Japan, be alert to **new airline rules** rolled out in July 2025 that affect all 23 Japanese carriers. Portable chargers now must be kept in your pocket or under the seat, not in overhead bins or checked luggage. Only two chargers are allowed if they’re between 100 and 160Wh, and larger devices over 160Wh are banned entirely, following recent fire incidents on planes. Inspect your power banks before travel to avoid unexpected confiscation and fines.

Entry into Japan has also been updated with the new Japan Electronic Travel Authorization (JESTA) system, similar to the U.S. ESTA program. Listeners from visa-exempt countries must now apply for travel authorization online before departure, speeding up airport entry and enhancing border security. For travelers from Taiwan, a pre-clearance pilot allows you to complete border checks at your home airport, reducing arrival wait times—this may expand to additional countries in the future. Make sure to check for any online application requirements well ahead of your trip to avoid issues on arrival.

On the ground, changes to Shinkansen (bullet train) travel affect how you plan your journeys. Starting March 15, 2025, most Nozomi Shinkansen trains have drastically reduced non-reserved seating, meaning listeners should reserve seats in advance, especially during holiday periods like Silver Week in mid-September, when seat demand spikes. Train companies are recommending booking well ahead, not relying solely on spontaneous travel.

Listeners should also stay up to date on new bans and entry requirements that have taken effect with Japan’s spike in tourism. These include restrictions on certain consumer goods, possible confiscation of items at customs, and areas where tourists may be restricted to preserve local lifestyles for residents. Information on these regulations can be found through Japan’s official tourism and government websites, as well as airlines and travel agencies.

In summary, traveling to Japan in late September 2025 offers unique cultural and seasonal experiences with calmer crowds and comfortable weather, but listeners must be prepared for typhoon season disruptions. Stay informed of the JESTA entry requirement, updated airline and rail rules, and any advisories regarding weather or transport. Flexibility and proactive planning will ensure a smooth and memorable trip in a country whose travel landscape continues to evolve.
