Know. Think. Try.

Three guides carry the three steps. They are drawn as punctuation marks rather than characters, because the same marks appear inside the articles.

• Know.Holds the “know” step. The answer sits in the first three lines of every article.
• Think?Holds the “think” step. How it works, what is often misunderstood, what the numbers can and cannot say.
• Try!Holds the “try” step. A small, safe experiment and a question to take to your family.

Each guide is its own directory. Wherever you start, it leads to the next one.

• The Why GuideThe answer first. Then how it works. · /en/why/
• The Jobs GuideWho a job helps, and the many roads that lead there. · /en/jobs/
• The Play GuideLearn the rules. Find the trick. Fix it yourself. · /en/play/
• The Body GuideA quick dictionary of nutrients and muscles. · /en/body/
• The Data GuideRead the differences and changes together, not just the average. · /en/data/

1. Never one road to a job

   Schools, licences, employment, regions, coming back to study later — routes are laid out side by side, including how to rejoin after a detour.

2. Numbers are not odds about you

   We explain what an exam result, a headcount or a registration figure actually counts, and never convert them into a child’s chances.

3. Simple words, unsimplified facts

   Language gets easier; the facts do not get more convenient. Illustrative examples are kept visibly separate from what has been verified. Every article carries its sources and the date it was last checked.

4. Safety and privacy come first

   No experiment that puts a child at risk, and no name, age or school required to read anything here.

The site is written in Japanese first. An article appears in English only after it has been written and checked in English — nothing is machine-translated behind the scenes, and no English URL exists for an article without English text. Much of what is here explains how things work in Japan, which is often the most useful part for a reader elsewhere.
