The geomagnetic field over Kukichūō is quiet. The planetary Kp index is 0.7 — about 0.5 as effective local exposure at this latitude — and the next 72 hours should stay comfortable, peaking near Kp 3.0 around Sat 12:00 PM local time.
Kukichūō sits at geomagnetic latitude 28.3° — and that latitude, not the city itself, decides how strongly a storm is felt: we estimate local exposure at ×0.82 of the planetary Kp. Auroras become plausible here from about Kp 9. All times on this page are shown in Kukichūō local time (UTC+9).

Official NOAA Kp forecast with a general wellbeing-risk estimate for weather-sensitive people.
A comfortable window. Good time for demanding tasks, workouts and travel plans.
General population-level guidance, not medical advice. Reactions are individual — a symptom diary shows what actually affects you.

No — the field is quiet. Kp is 0.7 right now, and the next 72 hours peak near Kp 3.0 around Sat 12:00 PM local time. Kp 5 or higher would count as a storm.
Realistically no. At geomagnetic latitude 28.3° the auroral oval stays far away even in strong storms — a sighting would take a once-in-decades event.
The Kp index itself is planetary — one number for the whole Earth. What changes is how strongly a place feels it: at Kukichūō's geomagnetic latitude (28.3°) we estimate the effective exposure at about ×0.82 of the planetary value.
Research is mixed, but many weather-sensitive people report headaches, fatigue or restless sleep during elevated activity. It is a possible correlation, not a diagnosis — the forecast above shows when the sensitive windows are, and a symptom journal shows whether they matter for you.
