Many households in Japan do a big clean before the New Year (年末の大掃除, nenmatsu no osoji). In Ehime, the hard jobs are the air conditioner, the range hood (the fan over the stove) and the bathroom, and many people hire a company. This guide compares three companies for those jobs: Duskin Service Master, Osoji Honpo and Kajitaku. It shows official prices, how many shops each has in Ehime Prefecture (and in Matsuyama City), parking charges and when to book. All prices include tax.
In short
- One wall-mounted air conditioner (no self-cleaning function): ¥14,300 at Osoji Honpo, ¥15,400 at Duskin, and ¥9,700 to ¥11,880 at Kajitaku, depending on the plan.
- Range hood and bathroom: ¥18,700 at Osoji Honpo, ¥19,580 at Kajitaku, and ¥22,000 at Duskin (the base price; larger jobs cost more).
- Duskin has 17 shops in Ehime Prefecture (7 in Matsuyama City) and Osoji Honpo has 11 (6 in Matsuyama City). Kajitaku has no shops and sells at one price across Japan.
- The official pages we read for all three companies are in Japanese and say nothing about English. None gives a year-end booking deadline.

1. What do the three companies charge?
Depends on the company
For one air conditioner, Osoji Honpo lists ¥14,300, Duskin ¥15,400, and Kajitaku ¥9,700 to ¥11,880 on the campaign prices shown on October 10, 2026. The ¥9,700 plan cleans only the outside cover and the filter; cleaning inside the unit starts at ¥11,880. For a range hood or a bathroom, Osoji Honpo (¥18,700) and Kajitaku (¥19,580) are close, and Duskin starts higher (¥22,000). Click a company name to jump to its section.
| Company | Air conditioner, 1 unit | Range hood / bathroom | Shops in Ehime |
|---|---|---|---|
| Duskin | ¥15,400 | From ¥22,000 / from ¥22,000 | 17 (Matsuyama 7) |
| Osoji Honpo | ¥14,300 (¥12,100 each for 2 or more) | ¥18,700 / ¥18,700 | 11 (Matsuyama 6) |
| Kajitaku | ¥9,700 to ¥11,880 (campaign) | ¥19,580 / ¥19,580 | No shops |
These are standard prices for a wall-mounted air conditioner without a self-cleaning function. Units with a self-cleaning function cost more. Kajitaku’s air conditioner prices are campaign prices; its regular prices are ¥10,780 to ¥14,300 (see section 4). Parking: Kajitaku pays for it; Duskin and Osoji Honpo may charge you if there is no space (see sections 2 and 3).
If you book all three jobs (one air conditioner, one range hood, one bathroom), adding the base prices gives ¥59,400 at Duskin, ¥51,700 at Osoji Honpo and from ¥48,860 at Kajitaku. The Kajitaku figure uses the campaign price of its Light air conditioner plan (¥9,700; regular price ¥10,780), which cleans only the outside cover and the filter, and excludes other discounts and extra fees.
2. Duskin Service Master: 17 shops in Ehime Prefecture
Depends on the company
Duskin’s standard price for a wall-mounted air conditioner is ¥15,400. Duskin has regional price pages, and the one you get after choosing Ehime in the area menu (its “B area” list) shows ¥15,400 for one unit and ¥25,300 for a set of two. With a self-cleaning function, a set of two is ¥47,300. Air conditioner cleaning and price list for Ehime (B area) (Duskin official, Japanese).
A range hood or hooded fan under 95 cm wide is ¥22,000, and each extra 15 cm adds ¥2,530. A bathroom with a floor under 3 m² and a ceiling under 2.4 m is ¥22,000, and larger rooms cost extra. Duskin says work on weekends, holidays and at night may not be accepted, or may cost extra. If your free days are only on weekends or holidays, ask the shop before you apply. Range hood and bathroom (Duskin official, Japanese).
A campaign runs for water-related jobs (bathroom, washroom, toilet, kitchen, range hood). If you book 2 or more of them, the total for those jobs is 8% off. Applications are open from September 14 to November 6, 2026, and the work must be done by November 13, 2026. A single job does not qualify, and the page says some areas and shops cannot offer it. The same page asks you to prepare a parking space for the service van, and says you pay for a paid car park if the van cannot park. It also says that if the shop has to use a paid ferry or bridge to reach you, the actual cost is billed separately. Water-related cleaning campaign (Duskin official, Japanese)
The Ehime Prefecture shop list shows 17 shops: 7 in Matsuyama City, 2 each in Imabari City, Saijo City and Shikokuchuo City, and 1 each in Niihama City, Uwajima City, Ozu City and Ainan Town (Minamiuwa District). One of the two Imabari shops is on Hakata Island (Hakata-cho). You apply on the Duskin website or by phone, and the shop contacts you later with the estimate and the date.

3. Osoji Honpo: 11 shops in Ehime Prefecture, ¥2,200 less per unit for 2 or more
Depends on the company
Osoji Honpo’s air conditioner cleaning (wall-mounted, no self-cleaning function) is ¥14,300 for one unit and ¥12,100 per unit when you book 2 or more together. With a self-cleaning function it is ¥24,200, or ¥22,000 per unit for 2 or more. Until November 1, 2026, a limited-time campaign lowers the one-unit price to ¥13,200 (¥11,000 per unit for 2 or more). Full disassembly cleaning is an option at ¥8,800. Air conditioner prices (Osoji Honpo official, Japanese)
Range hood and fan cleaning is ¥18,700 and takes about 2.5 hours. Bathroom cleaning is ¥18,700 and takes about 2 hours. The page says a range hood made 9 years ago or more may be refused, or the work may not be guaranteed, because the maker has stopped making parts. Range hood and bathroom (Osoji Honpo official, Japanese).
The Ehime Prefecture shop list shows 11 shops: 6 in Matsuyama City, 2 in Niihama City, and 1 each in Imabari City, Seiyo City and Masaki Town (Iyo District). The steps are a free estimate request, a phone call from the shop to set the date, and a final check of time, price and work when the staff arrive. The company says it normally charges only the quoted price, but you may pay a travel fee if you live far away, and a parking fee if there is no parking space.

4. Kajitaku: no shops, the same price in Ehime as everywhere
Depends on the company
Kajitaku, an AEON Group service, sells air conditioner cleaning in three plans for wall-mounted units. The regular prices for a unit without a self-cleaning function are ¥10,780 (Light), ¥14,300 (Standard) and ¥25,300 (Premium). On October 10, 2026 the page showed campaign prices of ¥9,700, ¥11,880 and ¥22,770. Light (30 to 50 minutes) cleans the outside cover and the filter and does not take the unit apart. Standard (60 to 150 minutes) also cleans the inside of the unit. The page does not give an end date for the campaign, so check the price on the booking screen. Air conditioner plans (Kajitaku official, Japanese)
Range hood and bathroom cleaning each start at ¥19,580, and take about 120 minutes. The company says the price is the same in every area, with no travel fee, and that it does not charge for parking, even in a paid car park. It can visit 3 days after you book at the earliest, and cannot come on the day you ask. You book on the website, or by phone at 0120-525-827 (10:00 to 16:00, except the New Year holiday). House cleaning prices and booking (Kajitaku official, Japanese)
One option is not offered in Ehime: the drain hose insect cap (¥1,650) excludes Ehime and the other three Shikoku prefectures. The air conditioner cleaning pages show no such exclusion for Ehime.

5. What matters when you choose in Ehime?
Depends on the company
Two company types are in this guide. Duskin and Osoji Honpo work through local shops, so the shop that covers your address gives the schedule and price. Kajitaku sells at one price in every area. Most shops are in Matsuyama City, so where you live decides which company is easy to use.
- Matsuyama City: 7 of Duskin’s 17 shops and 6 of Osoji Honpo’s 11 shops are here, so all three companies are easy to compare.
- Imabari City: Duskin has 2 shops (one on Hakata Island) and Osoji Honpo has 1. If your home is on an island, ask first whether they will come, and note that Duskin bills a paid ferry or bridge separately.
- Niihama City and Saijo City: Niihama City has 2 Osoji Honpo shops and 1 Duskin shop. Saijo City has 2 Duskin shops and no Osoji Honpo shop on the list. Kajitaku has the same price in any city.
- Parking: the companies visit by car. Kajitaku does not charge for parking. Duskin and Osoji Honpo say you may pay if the van cannot park, so tell them early if your apartment has no space.
- Shikoku option: Kajitaku’s drain hose insect cap is not available in Ehime.
- English: the official pages we read for all three companies are in Japanese and do not say whether English is available. Plan to book through the Japanese page or ask a Japanese speaker to help.
6. When should you book for the year-end?
Depends on the company
None of the three official pages gives a deadline for year-end bookings, so if you have a date in mind, ask for a quote or book early. Kajitaku says its cleaners work on weekdays, Saturdays, Sundays and holidays from about 8:00 to 18:00, except during the New Year holiday period, and that a date can be full. Osoji Honpo sets the date by a phone call from the shop. Two discounts end earlier than the year-end: Osoji Honpo’s air conditioner campaign on November 1, 2026, and Duskin’s water-related 8% off, which you must apply for by November 6, 2026.
The booking and estimate pages are in Japanese. If you use a browser translation tool to read them, check the date, the price and the work again on the final confirmation screen.
7. What should you check before you sign?
National Consumer Affairs Center of Japan
Important
In a notice of February 28, 2025, the National Consumer Affairs Center of Japan told people to get quotes from several companies and to check, before signing, whether insurance covers damage the work might cause. The notice includes a case where a cheap fan cleaning (¥5,000) led to a contract of about ¥600,000 after sales talk. It says you may refuse to sign if you do not accept the price or the explanation. It also advises asking the air conditioner maker about the cleaning method. If something goes wrong, call the consumer hotline 188, which connects you to a local consumer center. The notice does not say whether English is available.

8. Can you compare local cleaners yourself?
Depends on the provider
If you would rather compare individual cleaning shops than pick one of the three companies, Your Mystar is a booking site where you can search for cleaners. The site and its forms are in Japanese only, so you may need a browser translation tool or a Japanese speaker.
