Background
The Matsushiro Castle ruins lie in Matsushiro-machi, Nagano City; the castle was formerly called Kaizu Castle. Nagano City's castle history explains that the site connected with terrain such as former channels of the Chikuma River and became a defensive stronghold in the Warring States period; after Sanada Nobuyuki was transferred from Ueda to Matsushiro in 1622, the castle and the domain's centre of government gradually developed. Some of the stone walls, earthworks and moats you see today help you make out the castle's outline, but not all gates and bridges are original Edo-period structures: in its works from 1995 to 2004, Nagano City restored some buildings with reference to old maps and archaeological data. The castle site, together with the Sanada Residence, is designated a National Historic Site, while the Sanada Treasure Museum, the Bunbu Gakkō school and former samurai residences are spread across the wider Matsushiro district. This attraction page therefore centres on the physical castle site; the castle-town walking route should be linked from the Nagano city page, and not all Matsushiro facilities should be treated as one ticket and one building within the castle. The Battles of Kawanakajima have a historical connection with Matsushiro Castle, but literary details of single combat cannot be taken as direct historical evidence on site.
Local customs
- The castle site is an open historic site and park
- when walking, observe fences, areas under repair and path signs, and do not climb the stone walls or step into the moats. Historic buildings and exhibition facilities have their own visiting rules
- at the Sanada Residence and the Treasure Museum, check opening areas and tickets separately. When taking photos, avoid blocking residents and other visitors.
Religion & beliefs
- This is a historic castle site, not a place of religious worship
- there are temples and shrines elsewhere in the Matsushiro district, so if you extend your visit, respect each one's own faith and opening rules.

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.

Don’t DON'T
- Do not describe the gate and bridge rebuilt around 2004 as preserved in their original state to this day
- do not reduce the whole Matsushiro castle town to a single castle-site pin
- do not climb the remains or ignore repair barriers.
Locals appreciate DO
First use the explanations at the castle-site entrance to identify the honmaru (main enclosure), gates and earthworks, then walk to the Sanada Treasure Museum or the Sanada Residence, so you can understand the Warring States castle site and Edo-period domain government separately.

Practical info
Travel tips
- The Sanada Treasure Museum's official materials give the castle site's address as 44 Matsushiro, Matsushiro-machi, Nagano City. Take a bus bound for Matsushiro from the Zenkōji exit of Nagano Station
- the museum gives a journey of about 30 minutes, followed by a walk of about 5 minutes from the stop
- check the current timetable for actual services and stops. For the castle site alone with reading of the on-site explanations, allow about 30–60 minutes
- if you add the Sanada Treasure Museum, the Sanada Residence and the district route, allow half a day, and check tickets and opening hours for each facility separately. The castle site is generally open, but the accessible areas may be adjusted over the New Year period or during maintenance or works, so check the official facility page and Nagano City notices before you go. The castle site, Zenkōji and Togakushi Shrine are not on one walkable route
- from Nagano, plan them by area in separate sections. The photo shows the restored Kita-fumeimon Gate and cannot be used to prove that all the castle buildings are original.
