A Ryokan Babymoon in Japan: Onsen in Pregnancy, Kaiseki, Beds and Easy Inns

The short answer: a ryokan babymoon works well, and Japan's own onsen authority says pregnant women can bathe in hot springs, with care. Go in the middle of your pregnancy if your doctor agrees, book a room with its own bath and a bed rather than a futon, tell the inn about food when you book, and keep the journey to the inn short.

This guide is not medical advice. It brings together published guidance and the inns' own policies; check your plans with your doctor or midwife.

When to go, flights and insurance

The trimester. The American College of Obstetricians and Gynecologists says the best time to travel is mid-pregnancy, 14 to 28 weeks, when energy has usually returned and morning sickness has eased, and that travel after 28 weeks can be riskier (ACOG). It recommends a check-up four to six weeks before an international trip. That is general guidance; your doctor or midwife knows your pregnancy.

Flights. Airline cut-offs differ, so check your own carrier.

• JAL and ANA ask passengers within 28 days of their due date for a medical information form signed by a doctor within seven days of the flight, and those within 14 days must fly with a doctor (ANA, JAL).
• ACOG notes that most US airlines allow domestic flights until about 36 weeks, and that international cut-offs may be earlier.
• On a long flight, ACOG suggests an aisle seat, plenty of water, and getting up to walk; any journey of four hours or more raises the risk of blood clots, and pregnancy raises it further. Ask your doctor about compression stockings.

Insurance. ACOG suggests calling your health insurer four to six weeks before an international trip to ask whether pregnancy and newborn complications are covered abroad, and buying travel health insurance if they are not. Read the policy for pregnancy exclusions and the week cut-off before you buy. JNTO has a page on travel insurance for Japan.

Onsen and pregnancy

From 1982, the notices Japanese hot springs are required to post listed pregnancy as a reason not to bathe. That changed in 2014. Japan's Ministry of the Environment revised the bathing standards that year and removed pregnancy from the general list of conditions for which bathing is not advised, after finding no evidence that bathing harms a pregnancy (Japan Times, July 2014).

The ministry's English guide for visitors puts it plainly: pregnant women can bathe in onsen, but should not bathe for too long or in high temperatures, and should be careful of slippery floors (Ministry of the Environment, The ABCs for the Safe and Secure Use of Onsen, p. 18). In practice:

• Heat. Choose the cooler bath, or let a private bath cool. At Hatsuhana in Hakone you can add water to the open-air bath in your room to bring the temperature down (inn FAQ).
• Time. Shorter soaks, with breaks to cool off and drink water. Get out if you feel dizzy or light-headed.
• Floors. Wet stone and wood are slippery. Use the handrails, and go slowly on steps into open-air baths.
• Your doctor's view. Some inns say the same thing in their own words: Nanaeyae advises pregnant guests to watch for falls and light-headedness and to check with their doctor first (inn FAQ).

Why a private bath is easier. In a bath of your own you decide how long to stay in, you can let the water cool, there is no crowded wet changing room, and your partner is beside you. A reserved private bath (kashikiri) is the next best thing; our private onsen guide explains the difference.

Kaiseki while pregnant

Kaiseki is the ryokan's seasonal dinner of many small courses, and it often includes raw fish. Here is what the guidance says, so you know what to ask about.

• Raw and undercooked food. ACOG advises pregnant travellers not to eat raw or undercooked meat or fish, and to avoid unpasteurised milk products (ACOG). That covers sashimi, and may cover lightly seared beef. Discuss it with your doctor; advice differs between countries.
• Some large fish. Japan's health ministry advises pregnant women to limit kinmedai (splendid alfonsino), swordfish, bluefin tuna and bigeye tuna to about one 80 g portion a week, while yellowfin and albacore tuna and canned tuna need no special limit (MHLW advice on fish and mercury).
• Listeria. The ministry warns that listeria can grow even in the fridge, and that pregnant women should take care with ready-to-eat foods kept chilled for a long time, such as smoked salmon, raw ham and natural cheese made without heating (MHLW).
• Alcohol. Many kaiseki plans come with sake or a drinks pairing; ask for tea instead.

Tell the inn when you book, and again by email a week before. Inn policies are usually written for allergies rather than pregnancy, but they show how much notice to give:

• Gora Hanaougi asks for allergies and dietary needs at booking (inn).
• Hatsuhana suggests an alternative meal for eight named allergens if told after you book, and may not manage same-day requests (inn FAQ).
• Hakone Kowakien TEN-YU says it cannot adjust dinner for individual allergies (inn FAQ), but its plans include a buffet, where you choose what goes on your plate.

A simple line in your booking works: "I am pregnant and cannot eat raw fish or raw meat. Could the chef replace those dishes?"

Beds, steps and short transfers

Late in pregnancy, getting up from a futon on the floor and climbing in and out of deep tubs gets harder. Three things make the stay easier.

A bed. Many ryokan now have rooms with beds, often called Western-style or Japanese-Western rooms. Gora Hanaougi has bed-type rooms with two beds (inn); Izu Nagaoka Onsen Sanyoso has Japanese rooms with two beds and tells you to check which one you are booking (inn FAQ). Sinonomesou in Kinosaki has one step-free room with a raised tatami bed.

Fewer steps. Old ryokan have steps between rooms and up to baths. Hohoemino Kuyufu Tsuruya in Tendo has one all-flat room, HAKU, with its own open-air hot spring bath, plus an elevator; the inn says its other rooms have steps (inn). TEN-YU has two universal-design rooms among its rooms with an open-air bath (inn FAQ). Our accessible ryokan guide lists more.

Short transfers and fewer moves. Choose one inn for two or three nights rather than three inns in three nights. Pick one with a station pickup or a short walk: Gora Hanaougi is about a minute on foot from Sounzan Station; TEN-YU runs a free shuttle from Gora Station; Sanyoso runs a free shuttle, booked ahead, about five minutes from Izu-Nagaoka Station (inn FAQ). Hakone's upper villages are reached by mountain railway and cable car, so plan the luggage; our Hakone access guide covers sending your luggage ahead.
