Momofuda: Hyakunin Isshu

One poem a day — the surest way to make Hyakunin Isshu stick. Momofuda is a Japanese-language app for learning the classic anthology of 100 poems: study one poem deeply each day, lock it in with quizzes, and collect each mastered poem as a beautiful illustrated card. About five minutes a day.

■ Today's poem, in full Each day opens one poem with everything on the table: the original text, its reading, the kimariji (deciding syllables used in karuta), the poet, an original modern-Japanese translation, and a bite-sized note. Read it slowly, then head straight into the quiz.

■ Quizzes that lock it in Answer two four-choice quizzes (first half to second half, and the reverse) to earn the poem's card. The choices are carefully built so nothing leaks the answer — no length giveaways, no kimariji highlights. Miss one, read the explanation, and try again. A once-a-day hint (the kimariji) is there when you need it.

■ Reviews arrive right before you forget Learned poems return automatically at growing intervals — 1, 3, 7, then 14 days (spaced repetition). Usually four review questions a day, a few more on catch-up days; the whole daily session stays around five minutes. The app handles all scheduling — just show up.

■ Weak poems gather in one place Miss a poem twice in review and it lands in your Weak Cards list. Clear it with two straight correct answers in a drill set. You can always see exactly where you struggle.

■ A gallery of 100 poets Every card carries an original poet illustration. Poems arrive with a presentation rank (Tsune, Miyabi, Shu, Maboroshi) — better-known poems get grander reveals — and cards you fully graduate earn a gold frame through polish quizzes. Ranks are purely presentational: every card is obtained deterministically through daily play. There are no draws.

■ The Dojo: all 100 poems, anytime Separate from the daily lesson, the Dojo serves ten-question sets drawn from all 100 poems, as many times as you like — perfect before a test.

■ Catch up on missed days Revisit published poems in the archive, and catch up on uncollected poems from the last three days.

■ Premium (one-time) Remove ads, choose Dojo question ranges (by kimariji group, by rank, or weak cards only), catch up on every past daily poem, see detailed weak-card analytics, and claim reward perks without watching videos. A one-time purchase, not a subscription. Restore Purchases is supported.

■ Honest notes

• The app is currently in Japanese. Poems, translations, and all learning content are shown in Japanese, as in the screenshots.
• The poet illustrations are original artwork created with generative AI — imaginative portraits of historical poets, with no claim to accuracy of likeness.
• The translations and notes are written originally for this app. Where interpretations differ, we follow widely accepted readings.
• The original texts come from public-domain sources (Wikisource), cross-checked against two independent references; corrections can be delivered as data updates without an app update.
• Every card is obtained deterministically through daily play. There are no paid random mechanics (no gacha, no loot boxes).
• Ads are limited to two optional rewarded spots (Dojo extension and an extra drill set). The daily lesson itself has no ads.
