The Japan Shinkansen network avoided the large-scale suspensions often associated with major typhoons. JR East reported no canceled services on the Tohoku, Joetsu, Hokuriku, Yamagata, or Akita routes as of 5:47 a.m. on August 12. The Tokaido and Sanyo Shinkansen also operated without widespread planned suspensions, though travelers were advised to monitor conditions as heavy rain shifts westward across Japan. JR Central had previously warned of possible disruptions to the Tokaido Shinkansen due to heavy rain and strong winds, but no major service suspensions were implemented for the storm’s peak passage.
Air travel recovered swiftly after significant disruption on August 11. By Tuesday afternoon, All Nippon Airways (ANA) had canceled 58 flights and Japan Airlines (JAL) canceled six, affecting routes through Haneda and Narita airports. JAL’s cancellations impacted 864 passengers. On the morning of August 12, both ANA and JAL removed Typhoon No. 15 from their lists of airports expected to suffer weather-related disruption. JAL’s remaining weather warnings concerned poor visibility at regional airports in Kushiro, Tajima, Okinoerabu, and Yoron, rather than the typhoon itself. No airports in the Tohoku, Hokuriku, Kanto, Tokai, or Kinki regions were listed as being at risk from the storm.
Despite the broader recovery, localized problems remained on JR East’s conventional network, particularly in northern Ibaraki and Chiba Prefectures. The Suigun Line remained suspended in both directions between Hitachi-Omiya and Hitachi-Daigo due to a power outage caused by the typhoon. No estimate was provided for when this section would reopen, and no replacement bus service was available. Some northbound services between Mito and Hitachi-Daigo were also canceled. In Chiba, services on the Kururi Line between Kururi and Kazusa-Kameyama were canceled due to typhoon damage. JR East warned that the Sobu Main, Uchibo, Kashima, Sotobo, Togane, and Narita lines could experience delays, destination changes, or cancellations from the first trains of the day due to lingering heavy rain and strong winds.
Sea travel continued to face disruption even as air and rail services recovered. MOL Sunflower canceled its 7:45 p.m. departure from Oarai in Ibaraki Prefecture to Tomakomai in Hokkaido on August 12 due to rough seas associated with the typhoon. The corresponding evening services on August 11 had also been canceled. The company stated that its early-morning service from Oarai on August 13 is scheduled to operate. Highway operators in the Tokyo Bay area had previously warned that traffic restrictions may be imposed on the Tokyo Bay Aqua-Line and Joban Expressway depending on conditions, although no major road closures were reported as of the latest updates.
Other railway lines in and around Tokyo, including the Yamanote, Tokaido, Keihin-Tohoku, Yokosuka, Chuo, Keiyo, Musashino, and Takasaki lines, were operating normally by early Wednesday. The Utsunomiya Line, which had been suspended on Tuesday evening after a fallen tree blocked the tracks, resumed service, though some northbound trains experienced delays for inspections. The Joban Line and Hitachi and Tokiwa limited express services also returned to normal operation after earlier cancellations. Railway companies continued to urge passengers to check the latest information on their websites before departure, warning that localized weather damage and poor visibility could still cause sudden service changes.
