Keio University School of MedicineWe are a medical team engaged in research on NTM lung disease (NTM-PD). This team belongs to the division of clinical infectious diseases in Keio University, Tokyo, Japan.

Our ultimate goal is to expand the access to proper treatment for NTM-PD patients.

This survey marks our initial step toward achieving this objective.


NTM-PD is a condition caused by mycobacteria, a bacterial genus closely related to the one responsible for tuberculosis.

For a considerable time, the global health focus has primarily revolved around tuberculosis, overshadowing the prevalence of NTM. However, the incidence of NTM-PD is now on the rise, reaching unprecedented levels.

In Japan, for instance, there has been a dramatic increase, with cases rising by over 2.5 times in just seven years: from 5.7 cases per 100,000 people in 2007 to 14.7 cases per 100,000 people in 2014.

Given the current status of tuberculosis and NTM-PD, we firmly believe that the demand for comprehensive and in-depth research on NTM-PD is continually growing.
