Toilets and sewage services(廁所和下水道)

- The cleaning and upkeep of drain pipes on residential land is the responsibility of the land owner.
- Drain pipes rarely become blocked or damaged if they are used correctly.
- For more details, please ask your apartment building owner or caretaker.

There have been incidents of fraudsters posing as sewage inspectors to carry out unnecessary inspections of drain pipes on residential land, and charging people unfair sums of money and pressuring them into buying pharmaceuticals or electronic devices.
If someone recommends that you have your drain pipes inspected or repaired, refuse if there is no need for such work.
If you are suspicious about a person's credentials, ask to see a form of identification that will allow you to confirm his or her company name, employee name, and contact details, such as an employee ID card, and get in touch with your ward's Public Works Office. (Inquiries in Japanese only)

Anyone who uses running water at home or at work and discharges waste water into the public sewage system has their meter read once every 2 months, and is billed for the use of the sewage system.

The sewage charge is included in your water bill, so please check it on the statement you receive after your water meter has been read. If you pay your water bill through payment slips, please ensure to pay by the stated deadline.

Also, anyone who does not use running water (for example, well water) but discharges waste water into the public sewage system is still required to pay the sewage charge. In such cases, please contact the Accounting and Management Division, Environmental Planning Bureau (contact details provided below).

<Example calculation>
In the event that the discharge volume(2 months)is 30㎥(excluding tax)
118 yen(rate per㎥of 21-40㎥)x 30㎥-1,020 yen=2,520 yen

If you use running water but do not discharge any waste water into the public sewage system, you may be exempt from paying the sewage charge. For more details, please contact the Accounting and Management Division, Environmental Planning Bureau (contact details provided below).

- When installing a flush toilet, etc. in an area where there is no public sewage system, it is necessary to complete the procedures for the installation of a septic tank.
- Please submit notification in the event the manager changes due to moving house, etc., or if discontinuing use of the septic tank.
- It is the obligation of those managing the septic tank to have maintenance inspections, cleaning and legal inspections carried out on the septic tank.
