Background

Ōishi Park lies in the Ōishi district of Fujikawaguchiko Town and is a public park on the north shore of Lake Kawaguchi. The town lists play equipment, rest pavilions, a multipurpose square and the Kawaguchiko Natural Living Center in the park; it is neither the whole of Lake Kawaguchi nor the Lawson photo spot in front of the station on the south shore. Yamanashi Prefecture lists it as a public viewpoint for Mount Fuji, Lake Kawaguchi and lavender. The Flower Road has seasonal plantings, with different flowers and grasses in summer and autumn, but the state of the flowers and whether Mount Fuji shows itself both depend on the weather. The Natural Living Center, the farm-produce shop and the lakeshore path beside the park together form a short sightseeing area, and not all facilities should be described as keeping the same hours all year. The point of coming here is to see the local lake, agricultural tourism and the Mount Fuji landscape together from the north shore, not just to chase a photo from one fixed angle.

Local customs

  • The park is a public space shared by residents and visitors
  • stay on designated paths and photo areas, and do not enter planting beds or trample the flower fields. The town explicitly asks you to take your rubbish home and to keep dogs on a leash and clean up after them. Shoots that occupy space, use sets or are commercial require prior application under town rules
  • do not take the rules for ordinary visitors to mean that any shoot may freely take up space.

Religion & beliefs

  • Ōishi Park is a public lakeshore park with no religious rituals of its own
  • other places linked to Mount Fuji worship should be introduced separately, and the viewing park should not be called a temple or shrine.

  • 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

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.

Travel tips

  • Ōishi Park is on the north shore of Lake Kawaguchi, around 2525-11 Ōishi, Fujikawaguchiko Town, the address published by the town
  • from Kawaguchiko Station you should take a bus or other transport, and not estimate it as a walk from the station. Older transport information from Yamanashi Prefecture gives about 30 minutes by bus as a rough guide
  • routes, frequencies and actual journey times must be checked with the current operators. Allow about 45–75 minutes to stroll the park and photograph the lake
  • adding the Natural Living Center, the farm-produce shop and a short lakeshore walk, allow 1.5–2 hours. Mount Fuji may be hidden by cloud, and the flowering of lavender, kochia and other plants varies from year to year, so do not treat a promotional photo from one day as a weather guarantee. The town notes there are no rubbish bins in the park, so take your rubbish with you
  • dogs must be leashed. Some facilities and toilets have their own opening arrangements, and drinking fountains may be out of service in winter.
