Prohibited Substances and Methods


When a customer visits in person


We will install an interphone in front of the office, post information about the person in charge and work, and put the name of the person on the office desk so that customers can easily meet with the person in charge. When greeting a customer, he or she will first reveal his or her affiliation and name, and respond with kindness. If a representative is absent, the staff will be contacted as soon as possible. In this case, we will take care not to wait more than 5 minutes for the customer, Inevitably, if the person in charge is not able to handle the work, the employee who meets the customer or another employee will take care of the work immediately. (After the customer service is over, we will show you off outside the office.) If you are not feeling well, please contact (02-2045-9826) for assistance.


When a customer calls


When we answer a customer's phone call, we'll listen to them and explain them accurately and easily with a polite, soft voice "Thank you. This is OOO OO in the OOOO department." If you have any questions, the person who answers the phone will respond in person. If you need to connect a call to another employee, we will provide you with a direct phone number where you can be contacted and briefly communicate your call so that you do not repeat the same. If a representative is absent, we will deliver a note to call the customer as soon as possible. We will respond immediately when inquiring by phone, and we will respond by phone or e-mail within 24 hours if immediate response is difficult. At the end of the call, we will check if the question has been resolved, and after the customer hangs up, we will hang up the handset.
