Q. It looks like your formula for the Qibla calculation is faulty and misleading. To verify my comment, please check it in your website by setting your location to Tokyo, Japan.
A. For more clarification, I have provided you the following example for North America. This could be the case for your location too.
"The controversy of Qibla from North America surfaces from time to time. One group of people favors the direction of South-East, and another group favors North-East. Those who favor South-East are mislead by looking at the flat map with an argument that Makkah is south and east of North America. They are under a fallacy that the earth is a flat plane. Actually, it is more like a sphere floating in space of three dimensions. North Pole is a point from where every direction is south; there is no east or west from there. If you take a globe and stretch a thread from Alaska to Makkah, you will see that the thread passes through or close by North Pole. So, the Qibla from Alaska will be towards North. On a flat map, it appears to be South-East from Alaska, which is not correct." Please see the following figure.
This figure "is a true projection of the globe keeping Makkah at the center of projection. This projection allows us to draw a line from any place to Makkah and note the angle from the longitude lines. That gives the Qibla from the north. For example, take Alaska, and draw a line from Alaska to Makkah (as shown by the blue line). You will see that the line passes through the North Pole, so the Qibla from Alaska is due north. Curved lines on this map are longitude lines and they all meet at South and North Poles. They are not like latitude lines that are parallel to each other and do not meet. Take another example, Miami. The green line from Miami to Makkah makes an angle of about 56 degrees from the longitude line that goes to North Pole. So, the Qibla from Miami is 56 degrees to East from North. If that is confusing, then let us think that there is a very high minaret over Ka'bah, so high that it reaches the sky. Everyone would agree that if we can see that minaret, facing to that is the direction of Qibla." Reference: http://moonsighting.com/qibla.html
A red line from Japan to Mecca is drawn in the above figure. The angle between this line and the longitude line seems to be greater than 90 degrees, which means the direction of Qibla should be more than 90 degrees from the South clockwise, which is consistent with the Qibla direction on PrayTime.info and http://www.qiblalocator.com/.
We strongly recommend you to check this issue with your local Islamic centers too.
