Abstract
Allergic rhinitis is one of the most common allergic inflammation affecting 10-25 percent of the world's population, and its prevalence has increased over the last decade. Allergic rhinitis is not a life-threatening disease, but its persistent symptoms disturb patient's daily life. Moreover, it could be a risk factor to elongate infective inflammations in upper respiratory tract such as otitis media with effusion or chronic rhinosinusitis. In this manuscript, updated information on the pathogenesis of Japanese cedar pollenosis and its treatment strategy are introduced.
