Blood Pressure & Pulse Log 血圧・脈拍手帳

By Dr. Masa · physician licensed in Japan

Japanese doctors treat home readings as the real data — arrive with a log and you skip straight to the useful conversation. This page is that log: type today's numbers, see the trend, and print a Japanese-labelled sheet your doctor can read in five seconds.

Your data never leaves this phone. データはこの端末にのみ保存されます。 Readings are stored in this browser on this device only — nothing is sent to us or anyone else. That also means: clearing this browser's site data erases the log, and another device can't see it. Use Export CSV now and then as your backup.

Best practice: measure seated, after 1–2 min of rest — mornings within an hour of waking (before medication/breakfast) and again before bed. 朝は起床後1時間以内・服薬前、晩は就寝前。

When to act on the numbers: a home average of 135/85 or more across a week is worth a 内科 visit with this log — see the chronic conditions guide. A single reading of 180/120 or more with chest pain, severe headache, breathlessness or weakness is an emergency, not a logging matter. This tool records; it does not diagnose.
