風土記は、日本の47都道府県を地図から探索できる学習アプリです。都道府県を選ぶと、その土地がどこにあり、何で知られているか——食べ物、名所、自然、文化、歴史——を読むことができます。日本語と英語はヘッダーの切り替えでいつでも行き来でき、漢字にはふりがなを表示できます。Fudoki is a field guide to Japan's 47 prefectures. Choose one on the map and read where it sits and what it is known for — its food, its places, its landscape, its culture and its history. Japanese and English are one tap apart in the header, with furigana readings above the kanji.
地図のほかに、位置を当てるクイズと、行ったことのある都道府県を記録するマイマップがあります。アカウントは必要なく、記録はすべて自分の端末の中に残ります。Alongside the map there is a quiz that asks you to place each prefecture, and My Map, where you record the ones you have actually been to. There are no accounts — everything you make stays on your own device.
「風土記」は、713年に朝廷が全国の国々に命じて作らせた地誌です。それぞれの国について、産物、土地のようす、地名の由来、そして古老が語り伝えてきた話を書き記すよう求められました。A fudoki was a provincial gazetteer. In 713 the imperial court ordered every province to compile one, recording its products, the condition of its soil, the origins of its place names, and the old stories its elders still told.
ほぼ完全な形で今に残るのは『出雲国風土記』ひとつだけで、播磨・常陸・豊後・肥前のものは断片が伝わっています。名前そのものが「風」(その土地の気風)と「土」(土地)を「記す」という意味です。Only one survives in near-complete form — the Izumo no Kuni Fudoki, finished in 733. Fragments remain of four others: Harima, Hitachi, Bungo and Hizen. The name is literally a record (記) of the wind (風) and the earth (土): the character of a place, and the ground it stands on.
このアプリは、その小さな現代版です。国のかわりに47の都道府県について、その土地が何で知られているかを記しています。This app is a small modern one. In place of the old provinces it takes the 47 prefectures, and records what each place is known for.
地図から都道府県を選び、その土地の食べ物・名所・自然・文化・歴史を読みます。Pick a prefecture on the map and read its food, places, landscape, culture and history.
47都道府県すべての位置を、ラベルのない地図から当てるクイズです。A location quiz across all 47 prefectures. You are shown one prefecture's name in kanji and have to find it on an unlabelled map. Each has up to three attempts and is scored by how many you needed, so the final percentage reflects how well you actually know the country's shape — not how long you were willing to guess.
行ったことのある都道府県を記録して、自分だけの日本地図を作ります。Colour in the prefectures you have been to and build your own map of Japan. Each one is recorded at one of four depths — passed through, visited, stayed overnight, or lived in — because an overnight stay is a different thing from a day trip. The finished map saves as a single image you can share. It is anonymous and stored only on your device.
日本語と英語は二つのモードで、同時に並ぶことはありません。日本語を読んでいる間、英語が目の端に入ることがないということです。切り替えはヘッダーのボタン一つ。漢字にはふりがなを表示できます。Japanese and English are two modes, not two columns — you see one at a time, so the translation is never sitting in the corner of your eye while you are working through the Japanese. Switching either way is one tap in the header, which is the point: read a paragraph, check yourself against the English, come back. Furigana readings sit above the kanji, always on a phone and on hover on a desktop. The reading level is aimed at roughly JLPT N3–N2.
無料で、アカウント登録は必要ありません。クイズの記録もマイマップも、すべて自分の端末の中だけに保存されます。Fudoki is free and has no accounts. Your quiz session and your personal map are stored only in your own browser — there is no server holding them, and nothing about where you have been leaves your device. Full privacy notice.
