On October 3, 2026, we checked official websites for manufacturer services that offer online help with adult diaper selection. Alongside manufacturers offering chat support, this article introduces those with product-selection questionnaires.

Continence concerns can be difficult to discuss even with family or healthcare and care professionals. Anonymous chat and online tools can therefore be helpful.
Services from six major manufacturers
- Unicharm (Lifree): 24-hour “Charm-san” chat and diaper selection questionnaire.
- Livedo Corporation (Refre): AI chat available 24 hours a day, 365 days a year, and a diaper selection questionnaire.
- Kao (Relief): Adult diaper selection questionnaire available.
- Daio Paper (Attento): Offers “Easy Adult Diaper Selection.”
- Nippon Paper Crecia (Acty): Offers a product-selection questionnaire.
- Hakujuji (Salva): Offers “Simple Diaper Selection.”
Chat lets users type a question and receive a response. A selection questionnaire narrows product options through on-screen questions. To avoid confusing these questionnaires with chat support, their use is explained separately below.

Manufacturers offering product-selection questionnaires
Kao | Relief

The “Relief Concerns Chatbot” ended on June 30, 2023. The current “Adult Diaper Selection” questionnaire suggests products based on physical condition, continence circumstances and other answers. For personal assistance, check the “Fureai Dial” contact information on the official website.
Daio Paper | Attento

“Easy Adult Diaper Selection” is a tool that finds product options from answers to on-screen questions. It is not a chat consultation service.
Nippon Paper Crecia | Acty

The product-selection questionnaire shows options suited to the user’s condition. The website also has frequently asked questions about products and their use.
Hakujuji | Salva

“Simple Diaper Selection” helps find products through a series of questions. Also check actual physical condition, where elimination takes place, urine volume and change frequency when using it.

Questionnaire results are guides to product selection. Consult a healthcare or care professional if leakage or skin problems persist. Services can change, so check each manufacturer’s official guidance before use.
