Compute the date that is N business days before or after a given date, skipping Japanese national holidays plus weekends.

Search 110+ **Japanese traditional colors** by kanji, reading, romaji, or HEX. Filter by family (red / yellow / green / blue / purple / brown / neutral). Each entry includes the kanji name, kana reading, hex value, and a short note (madder root, Shinsengumi haori, Sen-no-Rikyu's favourite, etc). Drop a HEX and the tool returns the 8 closest wairo by RGB distance. Useful for design, fiction writing, traditional crafts, and kimono colour planning.

Convert between Gregorian years and Japanese eras (Meiji, Taishō, Shōwa, Heisei, Reiwa) with a mode toggle. Accepts year-only or full date input, handles 元年 (year 1) and era-boundary transitions like 2019-05-01 → Reiwa 1 (令和元年). No dictionary download required — runs entirely inside your browser.

Enter a year to see its full Eto (Sexagenary cycle of 10 Heavenly Stems × 12 Earthly Branches), the Earthly Branch + matching animal (Rat / Ox / Tiger / Rabbit / Dragon / Snake / Horse / Goat / Monkey / Rooster / Dog / Boar), the Heavenly Stem with its Five Element (Wood / Fire / Earth / Metal / Water) and Yin / Yang polarity (E / To), plus on'yomi and kun'yomi readings.

Tokenises Japanese text with kuromoji and wraps each kanji token in `<ruby>漢字<rt>かんじ</rt></ruby>` markup. Copy the source and paste it into WordPress, any CMS, or a Markdown article. Furigana can be hiragana or katakana, with optional `<rp>` fallback for non-ruby browsers. Runs entirely in your browser.

Verify the 5-7-5 (haiku) or 5-7-5-7-7 (tanka) mora pattern with kuromoji morphological analysis. Mixed kanji-kana input is parsed into katakana reading, broken into mora, and each line is checked against the target count — over and under shown line by line. Follows traditional rules: yōon (キョ, シャ etc.) absorbs into the previous mora; sokuon (ッ), hatsuon (ン), and chōonpu (ー) each count as 1.

Enter a count and a noun, and the tool suggests the right Japanese **counter word** (本 hon, 枚 mai, 匹 hiki, 台 dai, 杯 hai, 冊 satsu — 30+ counters) and shows the correct reading with *rendaku* (sequential voicing): `3 本` → sanbon, `6 匹` → roppiki, `20 歳` → hatachi. Common nouns (dog, car, paper, cup, book — 200+) are recognised automatically; otherwise pick from the full counter list. Great for JLPT learners, second-language speakers, and Japanese copy-editing.

Convert between historical Japanese eras (645 Taika through 1868 Keiō) and Gregorian years in both directions. Built-in dataset of 240+ pre-Meiji eras, including 元年 (year 1) and the rival Northern/Southern court eras of the Nanboku-chō schism (1331–1392). For Meiji onward use the era-convert tool. Year-level precision (the lunisolar calendar makes month/day mapping ambiguous). Runs entirely inside your browser — no dictionary download required.

Click to copy; component variants (心→忄, 水→氵, 艸→艹) are noted under each radical. Runs entirely in your browser.

Extract every CJK ideograph from your input and look up its stroke count in a table. Backed by 28,000+ characters from Unicode 17's Unihan kTotalStrokes — covers all jōyō kanji, JIS X 0208 levels 1 & 2, and most of CJK Extension A and Compatibility. Optional dedupe and stroke-order sort, with running total. Useful for studying, name-stroke analysis, or just checking your kid's homework. Runs entirely in your browser.

Convert Japanese text to hiragana using kuromoji morphological analysis. Choose between fully hiragana output, or a furigana mode that keeps kanji and adds hiragana ruby above. The dictionary downloads once and is then offline. Runs entirely in your browser.

Convert Japanese text to Hepburn romaji using kuromoji morphological analysis. Switch between full romaji and a ruby view, and choose macron long vowels (ō, ū) or literal doubled vowels (ou, uu). The dictionary downloads once and is then offline. Runs entirely in your browser.

Unlike emoji, kaomoji render identically on Slack, Discord, LINE, GitHub, and email regardless of fonts or platforms, so you can express emotion without worrying about Unicode compatibility. All data ships with the tool; no network, no upload — everything happens in your browser.

Convert between pre-war kyujitai (traditional kanji) and post-war shinjitai (modern Joyo Kanji) with a single mode toggle. Backed by 270+ pairs from the Joyo Kanji list (1981 / 2010 revision) and JIS X 0213 variant tables — 學↔学, 國↔国, 讀↔読, 廣↔広. Runs entirely in your browser.

Look up the Rokuyō (六曜) of any date — Sensho / Tomobiki / Senbu / Butsumetsu / Taian / Shakkō — and view a full month at a glance. Rokuyō is the traditional 6-day cycle used in Japan for picking auspicious days for weddings, funerals, moves, and store openings. Lunar conversion uses solarlunar (ISC); Rokuyō is computed as (lunar month + lunar day) mod 6. Includes month navigation and a per-Rokuyō meaning (Taian = all-day lucky, Butsumetsu = all-day unlucky, Tomobiki = 'pulls a friend' so funerals are avoided, etc.). Covers 1900-2099. Everything runs in your browser; no date information is uploaded.

From a date of birth (and optional reference date), figure out the Japanese school grade — preschool, elementary, junior-high, high-school, university — with proper handling of *hayauumare* (early-birth, 1 Jan – 1 Apr) and the 1 April / 31 March academic year. Also lists key milestones: elementary / junior-high / high-school entry and graduation dates.
