Women reportedly make up around 80% of the clientele for the service. While many of those hiring are in their 30s and 40s, users span multiple generations. Younger clients, in particular, have often sought guidance about career changes, job searches, or workplace relationships, and some have used the service for mock interview practice. One customer who had left a strong impression on Nishimoto was reportedly a terminal cancer patient who expressed a desire to "laugh in the end." Other requests have included help with decluttering, seeking advice on romantic matters, or asking an ossan to accompany an elderly parent living far away to medical appointments. Professional boundaries are considered essential to the service's operation. Nishimoto is said to verify the identity of every applicant and serves as an intermediary, passing along general information such as the customer's approximate location and age, while withholding real names. After each appointment, the ossan are strictly prohibited from initiating further contact with the client. Any individual who receives three complaints is dismissed from the service. Maintaining distance by limiting personal disclosures and steering clear of potential conflicts of interest is seen as crucial. Nishimoto has suggested that relationships with the ossan might feel unexpectedly comfortable—comparable, perhaps, to that with an uncle—thanks to this carefully preserved sense of space.
