The present study investigated influencing factors of acute mountain sickness (AMS) on Mount Fuji using questionnaires, and also complementary experimental study. In survey study, 395 people participated and the data of 376 participants were used for further analysis. Univariate analysis revealed that risk factors for developing AMS include; women (P=0.007, compared to men); less experience with climbing Mt. Fuji (P<0.001, compared to many experiences); overnight mountain climbers (P=0.035 compared to single-day climbers); and incidence participant with greater numbers of toilet break (P=0.013). Moreover, multiple analyses demonstrated that less experience was extracted to explain both the incidence (P=0.002) and the severity of AMS (P<0.001). In experimental study, arterial oxygen content was evaluated using a finger pulse oximeter (SpO2). SpO2 decreased gradually in accordance with increasing altitude, however, changes in SpO2 were not associated with the severity of AMS. Fluid inbalance, that is, the ratio between fluid intake and urine output, was associated with the severity of AMS obtained by quadratic curve regression (y=0.008x2+0.524x+9.733, r=0.841, n=9, P=0.025). Collectively, these preliminary data suggest that, in addition to less experience, fluid balance may also accentuate the severity of AMS.
