This month’s issue of Hypertension Research is a component of our Asia special issue, which has been running since April of this year. The highlight of this issue is the agreements of the Japanese Society of Hypertension with hypertension societies of 14 Asian countries/regions [1]. All 14 countries/regions that cooperated with us have their own hypertension guidelines. We report the blood pressure diagnostic criteria for hypertension and the target values for blood pressure lowering according to comorbidities in each country/region. In addition, salt intake is one of the most important factors in incident hypertension, and salt reduction has been considered one of the most important nonpharmacological therapies for hypertension treatment [2,3,4]. The average dietary salt intake and the target for achieving salt reduction in each country/region are reported. Based on this information, we note three statements that have been agreed upon by each country/region.

Additionally, Suzuki et al. reported the association of home blood pressure monitoring with hypertensive disorders of pregnancy in pregnant Japanese women [5]. Even in Japan, where home blood pressure monitoring is widespread, there have been very few studies on home blood pressure control during pregnancy. The sample sizes have been small compared to those of other cohort studies concerning home blood pressure measurement, and the results of this study are valuable. Abe et al. reported interesting results about the association between masticatory performance and hypertension in a cross-sectional study [6]. The results showed that decreased masticatory performance and tooth loss without the use of dentures were associated with the presence of hypertension in Japanese elderly subjects. Not only in Japan but also in other countries in Asia, the population will continue to age. As a nonpharmacological therapy for hypertension management, oral health may be a noteworthy subject.

Asia is also culturally and racially diverse. It is no exception in hypertension management. We look forward to making progress toward conquering hypertension in Asia by identifying similarities and recognizing the diversity of each country/region.
