Is Sleeping in Your Car Allowed at Michi-no-Eki and SA/PA in Ehime? MLIT and NEXCO West Japan Rules, and 9 RV Parks in the Prefecture

This article looks into whether you can sleep in your car where you stop when you get sleepy or arrive at night while driving around Ehime. It uses the official answers of MLIT and NEXCO West Japan, the parking places in Ehime where you can stay overnight, called RV Parks (RVパーク), and the rules on trash, idling and fire, all from the original text I checked. For the parking spaces at each station, see All 29 Michi-no-Eki in Ehime. For the expressway areas, see All Expressway SA/PA in Ehime.

MLIT answers “a nap is fine, overnight stays are basically discouraged”

The Ministry of Land, Infrastructure, Transport and Tourism (国土交通省, MLIT) has a page called the Road Consultation Room (道の相談室). It has a question and an answer about sleeping in a car at a michi-no-eki parking lot.

「道の駅」駐車場での車中泊は可能ですか？

Translation: “Can I sleep in my car in a ‘Michi-no-Eki’ parking lot?”

The answer is as follows.

「道の駅」は、ドライバーなど皆さんが交通事故防止のため24時間利用できる休憩施設であるので、運転の途中で疲労回復のために車内で仮眠をとるなどしていただくことはかまいません。ただし、駐車場など公共空間における宿泊利用は基本的にご遠慮いただいています※。

Translation: “A ‘Michi-no-Eki’ is a rest facility that drivers and everyone else can use 24 hours a day to prevent traffic accidents. So it is fine to take a nap in the car to recover from fatigue during a drive. However, we basically ask that people refrain from using public spaces such as parking lots for overnight stays.*”

The note to the answer says this.

※別途、宿泊利用のための駐車スペースを設けている「道の駅」もありますので、詳細は、各「道の駅」のホームページ等でご確認のうえご利用ください。

Translation: “*Some ‘Michi-no-Eki’ separately have parking spaces for overnight use. Please check the details on the website of each ‘Michi-no-Eki’ before you use them.”

This page does not say how many hours or what time divides a nap from an overnight stay. It also shows no update date.

The official pages of michi-no-eki in Ehime did not say whether sleeping in a car is allowed

For the 29 michi-no-eki in Ehime, I searched the following pages for the words “sleeping in a car” (車中泊), “nap” (仮眠), “idling” (アイドリング) and “RV Park” (RVパーク).

• The station pages of the Shikoku Regional Development Bureau (四国地方整備局) (29 stations)
• The station pages of the National Michi-no-Eki Liaison Council (全国「道の駅」連絡会) (29 stations)
• The official pages of each station (13 stations. Some pages are short.)

None of the pages had a sentence that allows or does not allow sleeping in a car. “Lodging facility” (宿泊施設) and “Campground, etc.” (キャンプ場等), listed on the Bureau and Liaison Council pages, are names of items for attached facilities. I have not checked the signs at the sites. The list of stations and each page are in the sources of All 29 Michi-no-Eki in Ehime.

On parking hours, the Bureau’s station pages say “available 24 hours” (24時間利用可能) for 28 stations (all except Sadamisaki Peninsula Museum (佐田岬半島ミュージアム)).

The station that explains how to use its parking lot on its official site is Yawatahama Minatto (八幡浜みなっと) (dated April 18, 2025).

八幡浜みなっとの駐車場は施設利用者及び道路利用者が一時的に休憩するための駐車場です。

Translation: “The Yawatahama Minatto parking lot is for users of the facility and road users to rest temporarily.”

そのため車を置いたままフェリーに乗船するなどの目的外の長時間駐車はお断りしております。

Translation: “For this reason, we do not accept long-time parking for other purposes, such as leaving a car and boarding a ferry.”

This notice refuses parking where people leave their car and take a ferry. It does not say anything about sleeping in a car itself.

Expressway SA/PA list parking for a long time beyond resting, sleeping outdoors and living in a car as prohibited acts

The FAQ of NEXCO West Japan (NEXCO西日本) explains SA/PA like this.

サービスエリア・パーキングエリアは高速道路を利用されるお客さまの休憩を目的としている施設です。

Translation: “Service Areas and Parking Areas are facilities for the purpose of resting for customers who use the expressway.”

The detailed prohibited acts are in the “Notes on Use” (ご利用上の注意) PDF (an illustrated notice) linked from the FAQ page. I read the notice as an image. Of its 10 items, the following relate to sleeping in a car.

• Under “acts that go beyond the purpose of resting” (休憩の目的を逸脱した行為), it says this.

  休憩の目的を逸脱した長時間・長期間駐車、野宿、野営又は車上生活等を行うこと。

  Translation: “Parking for a long time or a long period beyond the purpose of resting, sleeping outdoors, camping, living in a car, and the like.”

• Under “use of fire equipment” (火器の使用), it says this.

  みだりに火器を使用すること。また、許可なくキャンプ、バーベキュー又は花火等を行うこと。

  Translation: “Using fire equipment without good reason. Also, camping, barbecues, fireworks and the like without permission.”

• Under “noise and revving” (騒音・空ぶかし), it says this.

  車両による空ぶかし等騒音を発生させること。

  Translation: “Making noise such as revving a vehicle’s engine.”

• Under “bringing in household trash and the like” (家庭ゴミ等の持ち込み), it says this.

  家庭ゴミ、事業ゴミ、汚物及び危険物等の持ち込み、放置又は不法投棄を行うこと。

  Translation: “Bringing in, leaving or illegally dumping household trash, business trash, filth, dangerous goods and the like.”

For people who do a prohibited act, the notice says this.

なお、この禁止行為をされたお客さまへは、弊社から行為の中止又は退去を求める場合や弊社が関係機関への通報又は何らかの措置等を行う場合があります。

Translation: “In addition, to customers who do these prohibited acts, the company may ask them to stop the act or leave, and may report them to the related authorities or take some other measures.”

Neither this notice nor the FAQ says how many hours counts as “a long time.” The FAQ page names two areas where you can stay overnight, Dannoura PA (壇之浦PA) on the Kanmon Expressway and Miyajima SA (宮島SA) on the Sanyo Expressway, both with lodging facilities (highway hotels), and no facility in Ehime is named. For SA/PA in Ehime, see All Expressway SA/PA in Ehime. Kurushima Kaikyo SA (来島海峡SA) and Kamiura PA (上浦PA) on the Shimanami Kaido are managed by JB Honshi Expressway, and I have not checked their rules of use.

The Japan RV Association search shows 9 places in Ehime where you can stay overnight

One of the “parking spaces for overnight use” in the MLIT answer is the “RV Park” (RVパーク) certified by the Japan RV Association (日本RV協会). The Association’s guide says this.

RVパークとは、日本RV協会が『快適に安心して車中泊が出来る場所』を提供するために定めた条件を満たす車中泊施設です。

Translation: “An RV Park is a facility for sleeping in a car that meets the conditions set by the Japan RV Association to provide ‘a place where you can sleep in a car in comfort and safety.’”

The requirements for a facility include a toilet available 24 hours, a 100 V power supply, trash disposal, and the possibility of staying several days.

When I searched the Association’s RV Park search site (RV-Park.jp) with the prefecture set to Ehime, there were 9 results as of October 14, 2026. Prices are as shown on each page, and “~” is kept as shown.

Of the 9, 3 are inside a michi-no-eki. Prices and availability change, so check with each facility before you use it.

As a request for public parking lots such as michi-no-eki and SA/PA, the same page lists the “10 Manner Rules to Follow Strictly” (マナー厳守10ヵ条). Of the 10 items, the following 4 relate to this article.

• Do not stay for a long time (長期滞在を行わない)
• Do not camp (キャンプ行為は行わない)
• Do not dump trash illegally (ゴミの不当投棄はしない)

The day I checked, and what I could not check

I checked each page on October 14, 2026.

• Neither MLIT nor NEXCO West Japan gives numbers for how many hours counts as a nap or from what time counts as an overnight stay.
• The rules of each michi-no-eki in Ehime (whether sleeping in a car is allowed) were not written on the official pages I checked. I have not checked the signs at the sites. For the latest notice for a michi-no-eki, check the station’s official page or its reception desk.
• I have not checked the rules of use of JB Honshi Expressway (Kurushima Kaikyo SA and Kamiura PA).
• I have not checked the idling rules in the Ehime Prefecture ordinance.
• Prices, availability and booking methods of the RV Parks are as shown on RV-Park.jp. I have not made any bookings or inquiries. I have not listed the check-in time for Seiryu no Sato Hijikawa because RV-Park.jp and the Kurumatabi facility page differed.
• The MLIT and NEXCO West Japan pages may change. Where to check is gathered in Where to Check Ehime Road Information Before You Leave.
