Qibla direction in Isahaya
To face the Kaaba in Isahaya, turn to 288.4° measured clockwise from true north, which is west (18.4° north of west). The Sacred Mosque in Mecca lies 8,756 km away along the shortest path over the globe, and this is the direction the mihrabs of the mosques in Isahaya should follow.
Line up the top of your phone or compass with the green needle: it marks 288.4°, the Qibla of Isahaya. Phone compasses usually display true north, so a reading of 288° is all you need; a needle compass reads magnetic north and needs the local declination added or subtracted first.

How to face the Qibla in Isahaya
Stand where you will pray and find north first. Then turn towards west and move a further 18.4° towards north: the result is the bearing of 288.4°. A small error of a few degrees is forgiven by most scholars, but aiming simply at west would leave you about 18° off.
Facing the Qibla is a condition of the prayer. Whoever prays inside the Sacred Mosque faces the Kaaba itself; whoever is far away, as in Isahaya, faces its direction and makes a sincere effort to be accurate. A nearby mosque is a handy reference, because its prayer rows were aligned when it was built. Once you know the direction at home, a discreet mark on the wall saves you from checking again.
Why a flat map shows a different direction
This is a place where maps mislead badly: a straight line on a flat map from Isahaya to Mecca points to 261.9° (west), a full 26.5° away from the true Qibla of 288.4° (west). The map line keeps one compass heading and is 239 km longer than the great-circle route. Because the Earth is a sphere, the shortest way to Mecca from Isahaya first heads west, and that is the direction to face.
How is the figure of 288.4° obtained? From the coordinates of Isahaya (32.8411° N, 130.0431° E) and of the Kaaba (21.4225° N, 39.8262° E), spherical trigonometry gives the starting bearing of the great circle joining them. Mosque architects and astronomical Qibla tables rely on exactly the same calculation.
Distance from Isahaya to Mecca and Medina
Mecca is 8,756 km from Isahaya as the crow flies, and Medina, the city of the Prophet ﷺ, is 8,602 km away. A direct flight would take roughly 10 h 48 min, although most pilgrims from Isahaya connect through Jeddah or Medina airport.
Clocks in Isahaya run 6 hours ahead of Mecca all year. Prayer times, however, depend on the sun at your own location, so always use the prayer times of Isahaya rather than those of Mecca.
Finding the Qibla with the sun in Isahaya
On 85 days of 2027, the sun passes exactly through the Qibla direction of Isahaya while it is well above the horizon. At that moment, facing the sun means facing Mecca. The effect is most frequent in July (31 days); for example, on 15 May 2027 it happens at 18:35 local time.
On 254 days the sun stands exactly opposite the Qibla: then the shadow of any vertical object, a pole, a door frame or a plumb line, points straight towards Mecca. This is most frequent in March (31 days), for instance on 1 March 2027 at 07:57.

Twice a year the sun passes directly over the Kaaba, on 28 May 2027 and 16 July 2027. Both moments are in daylight in Isahaya: at 18:18 and 18:27 local time, face the sun and you face the Qibla exactly, anywhere in the city.
Isahaya compared with other cities
Compared with Tokyo, 941 km away, the Qibla in Isahaya is turned 4.7° further anticlockwise (288.4° against 293.0°), and Mecca is 718 km closer. The nearest city with its own Qibla page, Nagasaki (18 km), prays towards 288.3°, a difference of 0.1°.
Across the 154 cities in Japan on this site, the Qibla ranges from 288.1° in Sasebo to 295.3° in Kushiro, a spread of 7.2°. That is too large to use one national direction, so each city has its own bearing.
