Osawa Onsen Tojiya: ¥3,780 a Night, Futon Rented by the Piece

Yes, you can stay several nights at a hot-spring inn in Iwate, in a building about 200 years old, and cook your own meals. Tojiya, the self-catering wing of Osawa Onsen in Hanamaki, charges ¥3,780–4,380 per person a night when two or three people share a room (tax included). That price is the room and the baths only. The futon, the sheet, the pillow, the kotatsu and the stove are each rented by the day, so a winter night for two people sharing, with a futon set, a kotatsu and a stove, comes to about ¥4,900–5,500 each.

Hanamaki’s official English travel guide still says “From 3,000 yen”, with bedding charged separately and no amounts given. This guide works from the inn’s own Japanese price list, FAQ and booking pages, checked on 23 October 2026. I haven’t stayed at Tojiya myself. It is a different way of using a hot-spring town from the one I described for Beppu’s neighbourhood baths: here you rent the room by the night and build the rest yourself.

What ¥3,780 gets you, and what it doesn’t

¥3,780 rents your share of a tatami room and the baths.

Osawa Onsen’s own FAQ explains the system. Usually, as at Osawa Onsen’s main ryokan, Sansuikaku, a Japanese inn quotes one price per person with dinner and breakfast, and that price already covers the room, the service, the futon and the amenities. Tojiya’s basis is the old-style room-only stay (sudomari), so it keeps what the inn calls the old “stacking” method: room charge, then futon, then anything else you choose. Osawa Onsen calls Tojiya its jisuibu, its self-catering section.

Tojiya’s price list gives the room charge per person, per night, tax included. It says the price changes with the season but does not say which dates fall where.

The list has no line for four to nine people. On top of the room charge, the price list adds the hot-spring bathing tax of ¥70 a night. Check-in is 15:00 and check-out is 10:00. Each room has a TV, a fridge (empty) and a hot-water pot with tea things. Toilets and washbasins are shared and outside the room.

Futon, pillow and heater are each charged per day

Every rented item is charged again for every night of your stay, whether or not it is changed.

Tojiya’s price list gives these per-day prices, tax included, and says in one line that rental charges apply per day:

A full futon set (quilt, mattress, sheet and pillow) comes to ¥560 a night per person. The inn’s FAQ gives its own example: borrow two yukata for a three-night stay and you pay ¥220 × 2 × 3 = ¥1,320. It adds that guests on short stays who never swap their yukata are still charged by the day.

Heating is the old style too. The FAQ says summer means a fan and a paper fan, and winter means a kotatsu and a reflector-type stove.

The online winter plan costs a little more and saves the arithmetic

For two people sharing in winter, building the night yourself from the price list costs ¥4,905–5,505 each, and the online winter plan costs ¥5,910 each.

The plan also includes a yukata and a tanzen.

As the FAQ notes, most plans on the inn’s booking site already bundle the futon. On 23 October 2026 it showed these two room-only plans, among others, for the standard Tojiya rooms (6–8 tatami mats):

• Toji Plan Standard: futon set included, from ¥8,880 for two (¥4,440 each). The plan text says the yukata, the tanzen and all heating are extra.
• Toji Plan Winter (fuyu no jin): futon set, yukata, a haori or tanzen, kotatsu and stove included. On 23 October 2026 the calendar showed it on dates from December 2026, at ¥11,680 for two (¥5,840 each) or ¥6,540 for one person.

Neither plan includes meals or the ¥70 bathing tax. The booking site takes payment at the inn, not online. Both plans take bookings of one to seven nights. The booking site’s plan pages set the cancellation charge at 30% of the price two or three days before, 50% the day before, and 100% on the day or if you do not arrive.

Here is one winter night per person, for two people sharing, with the ¥70 tax included. The two price-list columns assume one kotatsu and one stove for the room, split between you.

Over seven nights that is ¥34,335, ¥38,535 or ¥41,370 per person. If you would also rent the yukata and tanzen every night, the price list comes to ¥5,400–6,000 a night, against ¥5,910 for the plan. The plan’s real advantage is that you book in one step, with the futon and heating already counted.

Travelling alone changes the sums. One person pays the higher single rate of ¥4,080–5,630 and rents the whole kotatsu and stove, which comes to ¥5,700–7,250 a night from the price list, and the single winter plan comes to ¥6,610 with the tax. Nights before a holiday can cost more: the inn’s booking site says that on those nights, and on special dates the inn sets, it used to take bookings only for two or more people, and now takes one person on a surcharged solo plan. On 24 October 2026 its plan list showed that solo plan from ¥8,880 for one person, with the futon set included and heating and the ¥70 tax extra. On the same day, its calendar showed the one-person winter plan on no Saturday between December and March, while the two-person winter plan did include Saturdays. A seven-night stay always includes a Saturday night, so check that night’s price before you add up a solo week.

Cooking for yourself in the shared kitchen

Tojiya has a shared kitchen with gas burners, a microwave, pots and tableware you can use free.

You bring the food and pay for the gas in ¥10 coins.

According to the inn’s FAQ, ¥10 buys 7–8 minutes on the coin-operated gas. The kitchen lends pots, kettles, a hagama rice pot, rice bowls, soup bowls, plates, chopsticks, spoons and cups. Knives are not kept in the kitchen: the facilities page says the front desk lends them, and asks you to wash what you borrow and put it back. You can bring your own ingredients. The shop is open 7:00–21:00 and sells seasonings, milk, beer, natto and tofu, and the facilities page says it can order in meat if you ask by the morning of the day before. The inn’s guide for overseas guests, in its Korean text, adds that at Tojiya you lay out and fold your own futon and wash the dishes you use.

If you only want rice, the inn will cook it for you. The inn’s FAQ calls this takidashi. The price list gives half a gō (about one bowl) for ¥100, one gō for ¥200, and miso soup for ¥150. Place your first order at the office. The facilities page lists the rice counter’s times as 7:00–7:30, 11:30–12:00 and 17:00–17:40, so if you arrive on the 17:55 shuttle, plan your first dinner at Yahagi or from the shop. You pay in cash at check-out, even though the inn takes most credit cards and PayPay for the stay itself.

On days you don’t want to cook, the inn’s restaurant, Yahagi, serves lunch 11:15–14:00 (last order 13:45) and dinner 17:15–21:30 (last order 21:00). Dishes on its recommended menu cost ¥1,100–2,000. Breakfast (7:30–9:00) is by reservation; the booking site’s plan text gives the breakfast set as ¥800, ordered at check-in. Tojiya also has a coin laundry, with washing machines at ¥200 a load, according to the facilities page.

Winter in a 200-year-old wooden building

The rooms are heated only by the kotatsu and stove you rent, and none of them is non-smoking.

Rooms lock only from the inside, and some do not lock at all.

The FAQ is plain about the rest. If smoke bothers you, ask when booking and the inn will deodorise the room as far as it can. There is no safe in the room, so the front desk keeps valuables. Toilets are shared and mostly Western-style, with a few Japanese-style ones; only some have a bidet seat. The booking site lists a separate block, Wakaba-so, as the only concrete building in Tojiya, with rooms that lock from the outside. Its online plans give you no choice of room.

The online winter plan’s own description says that in winter, the cold in the building and the rooms makes the kotatsu, the stove and a padded robe essential. If you drive, the FAQ advises winter tyres until early April.

The baths are the reason people come. Tojiya’s bath page lists three, all fed straight from the spring:

• Osawa no Yu, the mixed open-air bath by the river: 5:00–24:00, women only 20:00–21:00 every day. The women-only hour is suspended in the summer horsefly season. No showers.
• Kawabe no Yu, the women’s open-air bath: 6:00–24:00. No showers, and no shampoo or soap allowed. The page warns that it may be unusable in the cold of winter.
• Yakushi no Yu, the indoor baths, separate for men and women: open around the clock, except for cleaning. Showers, body soap and rinse-in shampoo.

Tojiya guests can also use Toyosawa no Yu, the semi-open-air bath at Sansuikaku, at any hour. According to the day-bathing page, it has showers, shampoo, conditioner and body soap.

If bathing naked with strangers is new to you, my guide to using a Japanese bath covers the basics.

How to book and get there

The inn’s own booking plans are listed only in Japanese.

The “English” link on the official site goes to a JTB booking site, JAPANiCAN, which lists Tojiya.

1. Choose your booking route.The JAPANiCAN listing is in English but shows prices only once you enter dates. The inn’s Japanese booking site has the plans above; its English screen listed no plans on 23 October 2026. You can also call Tojiya on 0198-25-2315 (8:00–19:00).
2. Book the shuttle at the same time.The shuttle is for staying guests. The access page asks you to reserve the pickup when you book, or at least four days ahead, giving the boarding point, time and number of people. Since 1 September 2026 each ride costs ¥100 per person (age 3 and up), paid at check-out.
3. Catch a fixed departure.Pickups leave Shin-Hanamaki Station (Tohoku Shinkansen, west exit, stop 2) at 15:10, 16:10 and 17:10, stop at Hanamaki Station 15 minutes later, and reach Osawa Onsen at 15:55, 16:55 and 17:55. Be at the stop five minutes early.
4. Check in by 20:00.The booking site warns that if you are later than the last check-in at 20:00, the booking is cancelled.
5. Reserve the bus back by 20:00 the day before.The return shuttle leaves Osawa Onsen at 9:57 and stops at Hanamaki Station, then Shin-Hanamaki Station.

Without the shuttle, the Iwate Kotsu route bus on the Yuguchi line runs from Hanamaki Station to Osawa Onsen in 25 minutes on the access page’s weekday timetable. The page says there are one or two buses an hour from Hanamaki Station. If you are weighing a rail pass for the trip north, I compared the regional passes.

What I could not settle

Quick answers

Should I stay at Tojiya if I have tattoos?

No. The inn’s day-bathing page says it refuses use of the inn to people with tattoos. Osawa Onsen’s private family baths are at Sansuikaku, and the inn’s overseas guide says they are for Sansuikaku guests only.

Can I wear a swimsuit or keep a towel on in the mixed bath?

No. The inn’s FAQ turns down both bath towels and swimsuits in the mixed bath, for hygiene. Women who would rather not bathe mixed can use the women-only hour at Osawa no Yu, Kawabe no Yu (which the bath page warns may be unusable in the cold of winter), or the separate men’s and women’s baths at Yakushi no Yu and Sansuikaku’s Toyosawa no Yu, both open around the clock.

Can I bring a rice cooker or my own futon?

Yes. The FAQ allows both. The inn charges for the electricity an appliance uses and may refuse some, so ask the self-catering desk before you pack one.

Prices, bath hours and shuttle times checked on 23 and 24 October 2026.
