Haiku and Modern Life — 17 Sounds in the Age of Commuting, SNS, and Smartphones

21st-Century Haiku, in the New Life

Of the 400 years of haiku history, the first 370 used mainly paper (books, journals) and face-to-face (kukai) as its media. But in the 30 years of the 21st century (roughly 1996-now), haiku is transforming as a verse form deeply rooted in digital environments and urban life.

The scenes in which modern poets write haiku are varied:

• On the commuter train — a few minutes’ composition on a smartphone
• SNS posts — verses posted on Twitter (X) and Instagram
• Online kukai — kukai with haiku friends across Japan on Zoom or Discord
• Smartphone haiku apps — kigo search, syllable checking
• YouTube and TikTok — recitation and explanation videos

These lie outside the 20th-century two-layer structure of head-led journals + face-to-face kukai — a new layer. The 21st-century haiku ecosystem runs on this three-layer structure (head-led journals + face-to-face kukai + digital).

Urban Seasonal Feel

Eighty percent of modern Japanese live in cities. For urban dwellers, Edo-era kigo (rice planting, rice harvest, kotatsu) exist only as knowledge. The modern urban seasonal feel includes:

Spring

• Cherry blossom forecasts (from the JMA)
• Hanami Instagram posts
• Graduation and matriculation suits
• La France pear (a modern imported autumn fruit)
• Golden Week

Summer

• Air conditioning (a modern necessity, a substitute for Edo’s suzushi)
• Air-conditioning sickness
• Uchimizu (revived in some places today)
• Tokyo’s evening downpour (heavy rain from asphalt heat)
• Semi-shigure — the cicadas remaining in urban parks

Autumn

• Autumn-leaf viewing (turned into tourism)
• Halloween (a modern autumn event, still being accepted as kigo)
• Rising saury prices (poor catches from warming)
• The “autumn of art”

Winter

• Christmas (representative of the modern winter)
• Year-end parties
• Year-end sales
• Heating
• Snow (rare in Tokyo)

New Year

• O-sechi (modernized and simplified)
• New Year’s hatsumōde (crowded)
• Digitization of O-toshidama

These “modern seasonal feels” are being gradually included in saijiki. But the traditionalist (Kyoshi) camp is cautious about admitting modern loanwords and katakana terms as kigo. Whether “Christmas,” “Valentine’s,” “Halloween” are formal kigo is a topic of debate in the modern haiku world.

SNS and Haiku — Compatibility with Short-Form Culture

17 sounds is about the same length as Twitter (X)’s 140 characters. Since 17 sounds is at most about 34-40 characters, Twitter’s 140 is more than enough to contain a haiku. This compatibility of “short-form platform × short verse form” underpins the SNS haiku boom.

Representative Twitter (X) Haiku Hashtags

• #俳句 — general haiku posts
• #毎日俳句 — a daily-verse challenge
• #SNS俳句
• #写真俳句 — photograph + haiku

Main SNS Poets

Examples of poets active on modern SNS:

• Kōno Saki (@sakukyou) — poet, head of Kagami, active in SNS communication
• Satō Ayaka (@sfmk) — young poet, Modern Haiku Association
• Iwata Kei — poet in his 20s, drawing attention on SNS
• Sekishiro — comedian and poet, in a duo of free-verse haiku with Matayoshi Naoki
• Matayoshi Naoki — comedian and novelist, known for free-verse haiku

The “Viral Haiku” Phenomenon

On Twitter, certain haiku sometimes go viral (thousands to tens of thousands of RTs):

• In 2020 during the pandemic, verses debating whether “mask” is a kigo spread widely
• Colloquial haiku by younger poets are widely shared
• Haiku by Akutagawa and Naoki Prize authors become topics

This is a spread of haiku that bypasses the central institutions of the haiku world — a new phenomenon of 21st-century haiku.

Instagram and Photo Haiku

Instagram is an SNS focused on the visual, and the “haiku + photo” combination fits well. Younger generations increasingly post haiku on Instagram.

Features of Instagram Haiku

• One photo + one verse — a modern version of haiga
• Connect to the world via #俳句 #haiku
• Displayed alongside English haiku — a venue for international exchange

The Photo-Haiku Movement

Novelist Morimura Seiichi (1933-2023) proposed photo haiku from the early 2000s, before full digitization. Morimura published many photo-haiku and systematized “the fusion of photograph and haiku.” After Morimura’s death, the tradition of photo haiku continues.

Online Kukai

Under the state of emergency during the pandemic (2020-2023), face-to-face kukai could not be held, and online kukai spread rapidly:

Platforms

• Zoom — kukai with faces on screen
• Discord — persistent text-chat kukai servers
• Google Docs — joint editing of submissions and selections

Benefits of Online Kukai

1. No geographic constraint — participation from anywhere in Japan
2. International participation — Japanese abroad and non-Japanese poets can join
3. Time flexibility — asynchronous participation possible
4. Records remain — logs of submissions and selections are preserved

Challenges of Online Kukai

1. Sense of the room — the pauses and silences of face-to-face kukai are hard to reproduce
2. Colloquial expression — online tends to be more colloquial and lighter
3. Subjectivity of judging — the atmosphere of face-to-face selection changes

After the pandemic, face-to-face kukai revived, but kukai run in hybrid form with online is settling in.

Haiku Apps and Kigo Search Tools

Digital tools that support modern poets (professional and amateur) in composition:

Haiku Composition Support Apps

• Apps for haiku composition (multiple) — syllable counting, kigo search
• Saijiki apps — offline kigo dictionaries

Kigo Search

• KUROSHIRO (kigo database, Modern Haiku Association)
• Electronic editions of saijiki — e-books from major publishers

AI Editing

• ChatGPT, Claude — for individuals to have haiku edited
• Some journals experimentally introduce — AI preselection → human selection

Haiku of the Younger Generation

A layer of haiku enthusiasts of the Gen Z (born 1997-2010) is growing up. Features:

1. Normalization of Colloquial Expression

Everyday colloquial expressions like “-da yo ne” or “-na kanji” appear naturally in haiku. Not seen in prewar or Shōwa haiku.

2. Katakana and Loanwords

Katakana words like “conveni,” “sumaho,” “elevator,” “mask” are taken in as kigo and materials.

3. Fusion with Tanka

Younger writers write across haiku, tanka, and free verse without treating the borders as strict. Influenced by modern tanka poets like Homura Hiroshi and Okamoto Yūya.

4. Compound Genre of Short Verse

Haiku + senryū + tanka + tweet poem are being written by young writers as one and the same short verse.

Examples of Young Poets

• Iwata Kei (2000-) — in his early 20s, representing the young side of the Modern Haiku Association
• Disciples of Kōno Saki
• Haiku Kōshien alumni in their 20s-30s

Many of these young poets do not belong to a head-led journal, taking SNS as their main venue. A large change from the 20th-century haiku system.

The Pandemic and Haiku (2020-2023)

COVID-19 brought some changes to haiku:

New Kigo Candidates

• Mask — debated as a modern “kigo”
• Remote work
• Acrylic partition
• Sanitization
• Social distance

Candidates for Signature Verses of the Age

Many poets in the early 2020s composed on “mask.” Whether these verses remain as “kigo of Reiwa” in a saijiki 30 years from now will be decided in the next 10-20 years.

Acceleration of Online-ization

The pandemic accelerated the online-ization of haiku by a decade. Online participation continued after the pandemic ended and became the new normal.

Change in the Meaning of “Shortness”

In the 17th century when haiku was born, artistic meaning lay in being “short.” In modern SNS short-form culture (Twitter 140 characters, TikTok 15 seconds), the “meaning of shortness” of the 17 sounds is changing:

Edo-Era “Shortness”

• Compressed density of background information through the 5,000 kigo
• Structure through the kireji
• The expectation that readers fill in the blank

Modern “Shortness”

• Length that fits at once on the smartphone’s vertical screen
• A unit easy to RT and spread
• Match to shortened attention span (matching the 3-8 seconds of human attention)

Here “the necessity of shortness is being revived for another reason.” That 400-year-old haikai still lives today is due to the modern power of shortness itself.

“One-Verse Focus” vs “Continuous Composition”

Edo and Meiji poets: several hundred to several thousand verses in a lifetime, each verse polished. Bashō 1,000, Buson 3,000, Issa 22,000 verses.

Modern SNS poets: one verse a day = 365 a year, tens of thousands over a lifetime. Less polish per verse, but a large volume accumulated.

Both stances coexist in modern haiku. “One-verse focus” (the tradition of the head-led journal) and “continuous composition” (the SNS way) hold different aesthetics.

The Modern Haiku Population

Estimated haiku population in modern Japan (around 2024):

• Readers and contributors of comprehensive journals: about 300,000-500,000
• Members belonging to head-led journals: about 200,000-300,000
• People posting haiku on SNS: about 1-2 million (overlap possible)
• Latent haiku enthusiasts (occasional writers): about 3-5 million

3-5% of the population engages with haiku in some form. This is far more than for other verse forms (modern poetry, tanka). It shows how deeply haiku is rooted in daily life.

Toward the Next Article

The single largest new element influencing modern haiku is generative AI. Overview article 19 gave a general treatment, but the technical details — the current LLM haiku-generation capability, prompt engineering, the limits of syllable calculation, the bias of training data, and the possibility of multimodal haiku — have not been touched. The next article digs into the technical details of haiku AI, including practical observation of modern LLMs (GPT-4o / Claude Opus 4 / Gemini 2.5, etc.). The true finale of this series.
