Nomad Camp Japan (netmaru.com) is a free, multilingual directory and interactive map for anyone who wants to camp, sleep in a vehicle, or find a legitimate overnight stop in Japan. It gathers campsites, free camping grounds, car-sleeping (shachuhaku) locations and roadside car-stay spots into one searchable place, adds a fireworks and festival calendar, and layers a growing library of practical travel guides on top. This article explains what the site offers, how many places are currently registered, and how to use it well when you are actually planning a trip.
What Nomad Camp Japan Is
The site exists to answer one hard question for travelers in Japan: *where can I legitimately spend the night outdoors or in my vehicle tonight?* Instead of hunting across dozens of Japanese-only municipal pages, reservation portals and map pins, it normalizes everything into consistent, traveler-oriented records — a name, a prefecture, a price snapshot, facilities, access notes, official links and map coordinates — and presents them in English, Japanese and Korean.
Right now the database holds 9,835 registered spots nationwide. Those break down into two big families:
- Camp Sites — about 6,161 spots: 5,342 paid campgrounds and auto-camps, plus 819 free camping grounds run by municipalities and local groups.
- Car Stays — about 3,674 spots: 3,301 free car-stay locations (a large share imported from the community-built 全国車中泊マップ / pcam.mobi car-sleeping map) and 373 paid RV parks and reservation-based car stays.
Alongside the spots there is a festival calendar with 213 events (103 fireworks/*hanabi* shows and 110 regional *matsuri*) and a library of 68 travel guides. All of it is a static site — fast to load, no account required to browse — with data drawn from public sources and clearly labelled as reference material to confirm before you travel.
Who It Is For
The site is built for two overlapping audiences. Overseas travelers get everything in their own language, with Japanese place names kept alongside so they can cross-check official pages, talk to staff, or type a name into a car navigation system. Domestic campers and car-stayers get a single map that mixes paid campgrounds, free sites and roadside stays that would otherwise live on separate services. Whether you are a solo cyclist looking for a cheap tent pitch, a family booking an auto-camp, or a road-tripper hunting a quiet michi-no-eki for the night, the same map and filters work for you.
The Interactive Map and How to Read It
Open the map and you see spots plotted across Japan. As you pan and zoom, the list on the side updates to show only what is inside the current map view — so the map itself acts as your geographic filter. Zoom into a valley or a coastline and you get just the spots there; zoom out to compare a whole prefecture. Each pin opens a quick summary, and every result card links through to a dedicated detail page.
The two scope buttons at the top — Camp Sites and Car Stays — switch which family of spots you are browsing, and the choice is reflected in the URL so you can bookmark or share a filtered view. You can also sort results, including by nearest to my location once you allow location access, which is handy when you are already on the road and need something close.
Search and Filters
There are two places to filter, and they are worth learning because they save a lot of scrolling.
On the home page, a compact search block lets you narrow before you even reach the map:
- A search box for an area or a spot name.
- A prefecture selector (All Japan, or one of the 47 prefectures).
- A category filter: All categories, Free Sites, Free Car stays, Camp Sites, or Car Stays.
- A price filter: All prices, Free, or a ceiling of ¥3,000 / ¥5,000 / ¥10,000 / ¥30,000 or less.
- A Google rating filter: any, or 3.0+, 3.5+, 4.0+, 4.5+.
Results here are ranked by rating and review count, so the strongest-reviewed places float to the top.
On the map view, the filter bar carries a matching set tuned for exploring:
- Search by area or spot name.
- Prefecture.
- Status: any, Free / verify, Paid, or Closed.
- Price: Free, ¥3,000 / ¥5,000 / ¥10,000 / ¥30,000 or less, or All prices.
- Google rating: any, 3.0+, 3.5+, 4.0+, 4.5+.
- Plus the map viewport itself — only spots within the visible bounds are listed — and the category/scope toggle between Camp Sites and Car Stays.
Combine them freely: for example, Nagano + Free + 4.0+ rating, then pan the map to the exact valley you want.
Camp Sites vs Car Stays, Free vs Paid
Understanding the two scopes helps you filter with intent:
- Camp Sites are places to pitch a tent or park at an auto-camp — paid campgrounds with facilities, or free municipal grounds. Use these when you want to actually set up camp, cook, and stay put.
- Car Stays are places to sleep *inside* a vehicle — free roadside stops (many are michi-no-eki style locations from the community car-sleeping map) and paid RV parks. Use these for a quiet overnight while on the move, where outdoor gear and cooking are usually not appropriate.
The free vs paid distinction cuts across both. Free spots (roughly 4,120 of the total) keep costs down but often come with fewer facilities, seasonal closures, or resident-only rules — so verification matters most here. Paid spots trade money for reliability: reservations, toilets, showers, power and clearer rules.
Spot Detail Pages
Every spot has its own page, and this is where you make the real decision. A detail page can include:
- Access to campsite — how to reach it and where to park.
- Shared facilities and equipment, and nearby facilities — toilets, water, showers, shops, onsen, and so on, shown with clear icons.
- The address and map coordinates, with a link back to the map view.
- A Google rating snapshot — stored as non-live reference data, so treat it as a hint rather than today's live score.
- Official and booking links — the campsite's or municipality's own page, and reservation sources where available, so you can confirm current rules and prices.
- Source notes describing where the record came from.
- Traveler notes — shared notes from signed-in travelers (Google sign-in, no passwords stored), which can add real-world detail you will not find on an official page.
- A Save favorite button to keep a shortlist.
- A Report a change form, so you can flag a closure, price change or error and help keep the data honest.
- A language switch (EN / JP / KR) that swaps the whole page, keeping the Japanese name visible for cross-checking.
The Fireworks and Festival Calendar
Japan's summer and autumn are defined by *hanabi* (fireworks) and *matsuri* (festivals), and they hugely affect where you can stay: popular dates fill campgrounds and close roadside lots early. The festival calendar currently lists 213 events — 103 fireworks displays and 110 regional festivals. You can view them as a calendar or on a map, and filter by type (fireworks vs festival) and prefecture. Use it to line up your camping or car-stay dates with an event you want to see — or to deliberately avoid the busiest nights.
Guides and the Blog
The guides section collects 68 practical articles on everything from verifying a free campsite and booking paid sites, to car-sleeping etiquette, michi-no-eki overnight rules, regional camping guides, seasonal safety (typhoons, winter, rainy season), and festival-season planning. Each guide is written in all three languages. Read a couple before your trip and you will avoid the most common beginner mistakes.
Multilingual Support
The whole site is available in English, Japanese and Korean, with real per-language URLs under /ja/ and /ko/ (plus hreflang tags) so search engines and language switchers land you on the right version. Place names keep their Japanese form alongside the translation, which is exactly what you need when a road sign, a navigation system or a staff member only speaks Japanese.
A Practical Planning Workflow
Here is a workflow that turns all of the above into an actual trip:
- Pick your area. Filter by prefecture, or just pan and zoom the map to the region you are heading to.
- Choose the kind of stay. Set the scope — Camp Sites if you want to set up a tent, Car Stays for a night in the vehicle.
- Filter by budget and quality. Add a price ceiling (or Free) and a Google rating minimum such as 4.0+ to cut the list to strong candidates.
- Open the detail pages. For each shortlisted spot, check access and parking, facilities (toilets, water, power), the address, and the official or booking link.
- Confirm on the official source. Follow the official/booking link and verify current rules, prices, reservation requirements and any seasonal closure — snapshots and ratings here are reference data, not a live feed.
- Check the festival calendar. Cross-check your dates against the festival calendar; if a big *hanabi* or *matsuri* falls nearby, expect full lots and book earlier or pick a backup.
- Save favorites and read traveler notes. Save your top picks, read shared traveler notes for on-the-ground tips, and keep a second-choice spot within about an hour's drive.
- Read a relevant guide. Skim the matching guide — free-site checks, car-sleeping etiquette, or seasonal safety — before you go.
Tips for Getting the Most Out of It
- Always verify before you travel. Ratings and prices are snapshots, and free sites in particular can be seasonal, damaged, or closed. Five minutes on the official page saves a wasted drive.
- Keep Japanese names handy. They make car navigation, official pages and asking for directions far easier.
- Respect the free stuff. Free campgrounds and car-stays stay open because travelers behave well — arrive quietly, take one space, and leave no trace.
- Report what you find. If a spot has closed or changed, use Report a change so the next traveler benefits.
- Plan around events, not into them. Use the calendar to enjoy a festival on purpose, or to steer clear of the packed nights around it.
Used this way, Nomad Camp Japan turns a scattered, mostly-Japanese landscape of 9,835 places to stay into a single map you can actually plan a trip around.
