Quick Japan travel tips on X

Japan travel posts on X are clustering around one problem this week: how to get through Golden Week with cheaper bookings and fewer airport surprises. (travel.rakuten.co.jp) (ana.co.jp) Rakuten Travel is already running its 2026 Golden Week booking push on its official site, with destination pages for Okinawa, Hokkaido, Kyoto, Tokyo and other domestic trips. The company’s travel portal also lists limited-time Golden Week campaigns, including offers tied to points and coupons. (travel.rakuten.co.jp 1) (travel.rakuten.co.jp 2) All Nippon Airways, or ANA, is pushing the other side of the trip: baggage rules. Its current guidance says passengers can bring one carry-on bag and one personal item into the cabin, and personal items must fit under the seat in front. (ana.co.jp 1) (ana.co.jp 2) The timing is tied to Japan’s 2026 holiday calendar. Golden Week starts with Showa Day on April 29 and includes Constitution Memorial Day on May 3, Greenery Day on May 4, Children’s Day on May 5 and a substitute holiday on May 6. (www.ncd.mhlw.go.jp) (japan.travel) That stretch is one of Japan’s busiest travel periods, when domestic demand spikes and transport hubs get crowded. Japan National Tourism Organization says business hours and closures can vary by region and business type during holiday periods, adding another layer for travelers planning last-minute trips. (japan.travel) (www.japan.travel) ANA’s newest rule change is especially relevant for travelers carrying backup chargers. For flights boarding on or after April 24, 2026, ANA says power banks cannot go in checked baggage, must be 160 watt-hours or less, and are limited to two per person. (ana.co.jp 1) (ana.co.jp 2) The airline also says passengers should insulate power-bank terminals with tape or a plastic bag to prevent short circuits. Charging a power bank from an in-flight power outlet, or using a power bank to charge another device on board, is prohibited under the updated guidance. (ana.co.jp) (ana.co.jp) ANA’s restricted-items pages add that lithium-ion batteries, lighters, sprays, smart baggage and electronic cigarettes all come with conditions for carry-on or check-in. The airline says codeshare flights can follow another carrier’s baggage rules, so travelers need to check the operating airline before departure. (ana.co.jp) (ana.co.jp) For travelers scrolling X for quick answers, the pattern is straightforward: book early if you still want Golden Week inventory, and recheck airline baggage rules before heading to the airport. The closer the calendar gets to April 29, the less room there is for mistakes. (travel.rakuten.co.jp) (ana.co.jp) (www.ncd.mhlw.go.jp)
