so that you don’t cast a shadow with your own hand when writing notes
In Japan, because right-handed people are the majority, placing windows on the left side of classrooms lets natural light come in from the left, preventing the paper from being shaded by one’s own hand when writing. This helps keep the field of view bright and makes it easier to concentrate on learning. In the past, when lighting was not as bright as it is today, the placement of windows was an important design consideration.

Which prefecture is the birthplace of the tear-off (daily) calendar?
- Tokyo Metropolis
- Osaka Prefecture
- Kyoto Prefecture
- Hokkaido
See the answer
Osaka Prefecture
The tear-off daily calendar is said to have originated in Osaka Prefecture. During the Meiji era, a printing company in Osaka devised and put into practical use a calendar format in which you flip a page for each day. In Osaka, which had developed as a merchants’ city, managing daily schedules and transactions was crucial, so the daily tear-off format was highly valued. Today it has spread nationwide, and various types—such as versions featuring proverbs and famous quotes—are widely appreciated.
It’s said that green is good for the eyes—but why?
- Because it has a relaxing effect.
- Because it's a color that doesn't strain the eyes.
- Because the wavelength of visible light is short.
- Because green is the color of the forest
See the answer
Because it's a color that doesn't strain the eyes.
The wavelength of visible light that appears green lies in the middle range, and it is said to be perceived without straining the eyes. This is a major reason why green is considered good for the eyes. Incidentally, in color psychology, green is believed to stabilize the mind and body and help ease tension. It’s also said that looking at greenery in the distance is beneficial for relieving eye fatigue.
