Background

Nakanoshima is a long, narrow sandbank in Kita Ward, Osaka, between the Dojima and Tosabori rivers, about 3 km from east to west. Together with Dojima to the north and Kitahama to the south, it is one of Osaka's traditional business centers, home to Osaka City Hall and the Bank of Japan's Osaka Branch. Modern buildings are concentrated on the island: the Osaka Prefectural Nakanoshima Library was donated by the Sumitomo family and opened in 1904, and its building is an Important Cultural Property of Japan; the Osaka City Central Public Hall originated in a donation of one million yen by stockbroker Iwamoto Einosuke in 1911, and its red-brick exterior, also an Important Cultural Property, is the symbol of Nakanoshima. The western part of the island is a cluster of cultural facilities: the National Museum of Art, Osaka moved here in 2004 into a building designed by architect César Pelli with all its galleries underground, and next door the Nakanoshima Museum of Art, Osaka collects modern and contemporary art and design.

Local customs

Nakanoshima is good for walking: Nakanoshima Park at the eastern end has a rose garden, the middle section has the Public Hall, the library and City Hall, and the western section has the museum cluster. There are many riverside paths and bridges, and taking a water bus to view the buildings from the river is another way to experience Osaka as the "City of Water".

Religion & beliefs

  • Nakanoshima is dominated by secular buildings and has no particular religious rules
  • the Central Public Hall and the library are public facilities still in use, so please do not make noise in reading rooms or meeting venues. When visiting nearby shrines such as Osaka Tenmangu, follow shrine etiquette for purifying your hands and bowing.

No photography and no eating or drinking in the permanent gallery of the Okinawa Prefectural Peace Memorial Museum

Do

  • Put away your camera, food and drinks before entering the permanent gallery
  • For the special exhibition gallery and the children's gallery, check the notices of the day to see whether photography is allowed
  • If you need to eat or drink, go to the areas designated by the museum, such as the outdoor colonnade

Don’t

  • Do not take photos or videos in the permanent gallery
  • Do not eat or drink in the permanent gallery, and do not have meals in other areas of the museum either
  • Do not extend the permanent gallery's photo ban into a photo ban across the entire park

The museum's 2026 visitor guide explicitly prohibits photography, eating and drinking in the permanent gallery and asks visitors to check the restrictions for other galleries separately; follow the museum's instructions on site.

Japan: At fireworks festivals, don't tape off spots in advance, and never fly drones

Do

  • Spread your sheet where there is actual space when you arrive, leaving room for neighbours
  • Follow police and staff directions and move with the crowd
  • Bring plenty of water and cooling gear to prevent heatstroke
  • Riverbanks have lots of insects, so bring repellent
  • Festivals usually go ahead in light rain, so bring a raincoat
  • Take your rubbish home

Don’t

  • Don't mark spots in advance with tape or spray paint on roads or in parks
  • Don't fly drones
  • Don't use selfie sticks in crowds; the Sumida River festival bans them
  • Don't stop in the middle of the path to watch and block the flow

Spots marked in advance are cleared by the organisers, and flying drones is prohibited by law. City-centre festivals run one-way crowd flows, and going against the flow or stopping can cause dangerous crushes.

Mixed, open-air and private baths: read the signs, don't stare, never take photos

Do

  • Check the signs before entering; mixed baths are clearly marked, and joining is entirely your choice
  • Most mixed baths are nude only, with no swimwear; some allow or lend special bathing wraps or towels, so follow the bath's rules
  • If you prefer not to bathe mixed, use the separate men's and women's baths or a private bath
  • Outdoor baths are slippery and the temperature changes sharply; hold the handrails when moving
  • Use a private bath only within your booked slot and leave on time
  • Tohoku and other regions still have many therapeutic hot springs with mixed bathing; for long therapeutic stays, follow the ryokan's and your doctor's advice

Don’t

  • Don't stare at other bathers, strike up conversations, or linger to watch
  • Don't take photos or videos in the bath area
  • Don't overstay a private bath; the next group is waiting

Mixed bathing works only because bathers keep their eyes to themselves; staring or taking photos will get you asked to leave, and filming others in a bath may break local law.

Stay off private land, and ask before photographing children or people

Do

  • Ask parents' permission before photographing their children
  • Ask geiko, maiko, and other working people before photographing them
  • Check for 撮影禁止 (no photography) signs, and ask staff if there are none
  • Photograph trains and stations themselves without disrupting operations

Don’t

  • Do not enter private homes or land for a shot
  • Do not photograph the inside of homes
  • Do not aim your camera at individual passengers on trains or buses
  • Do not step into rice paddies, flower beds, or along railway tracks for photos
  • Do not use selfie sticks or tripods in crowds or dangerous spots
  • Do not chase or stop geiko or maiko

Trespassing on private land is illegal and can get you told to leave or to delete your photos. Shooting in no-photo areas will be stopped, and photographing children is seen as an invasion of privacy.

Bathe nude in the onsen and keep your towel out of the water

Do

  • Bathe fully nude, without swimwear or underwear
  • Rest your small towel on your head or the edge of the bath
  • Tie up long hair so it stays out of the water
  • Enter the bath slowly and keep quiet
  • Leave your phone in the locker
  • Keep your first soak short, and dry off before returning to the changing room

Don’t

  • Do not dip your towel into the bath
  • Do not swim, dive, or talk loudly in the bath
  • Do not take photos anywhere in the bathing area
  • Do not wrap your yukata right side over left; that is how the deceased are dressed

Most of these are written bathhouse rules. Breaking them gets you a reminder from staff, and in serious cases you may be asked to leave. Soaking too long can also make you dizzy.

Practical info

Travel tips

  • Allow half a day: about 1.5 hours for the Central Public Hall and the library in the eastern section, and 2–3 hours for the art museums in the western section (exhibitions extra). Take the Keihan Nakanoshima Line to Naniwabashi, Oebashi, Watanabebashi or Nakanoshima Station, or take the Osaka Metro Midosuji Line to Yodoyabashi Station and walk. Opening hours, closing days and exhibitions of the public hall, library and art museums are subject to each facility's official website
  • some exhibitions require reservation or separate tickets. Combine with the modern buildings around Kitahama and Yodoyabashi and the Osaka Tenmangu Shrine, and in the evening eat around Kitashinchi or Fukushima. It is crowded during the spring rose garden bloom and the autumn foliage season, and at weekends the art museums may have queues.
