Summer Kigo — 150 Words from Rikka to Yūyake
Summer kigo, spanning the three months from Rikka (around May 5) to Risshū (around August 8) in the old calendar. Traces 150 words of summer in seven saijiki categories — season (Rikka, Suzushi, Taisho), sky (Samidare, Kaminari, Yūdachi), earth (Natsu no umi, Aota), life (Taue, Hiyayakko, Yukata), events (Tango, Tanabata, Bon), animals (Semi, Ayu, Ka), plants (Banryoku, Himawari, Yuri) — each with representative verses.
The Range and Hon’i of Summer
The seasonal range of summer (natsu) is the three months from Rikka (around May 5) to Risshū (around August 8). In the modern solar-calendar sense, “high summer” is July-August; but in haiku, summer begins already in May.
The hon’i of summer is “vigor” and “openness”:
- The season when everything grows lush and heat and light abound
- Contrasts of “cool,” “hot,” “stillness,” and “sound” form the core of its seasonal feel
- Cicada voices, thunder, evening showers, yukata, Bon dance — summer is the season of sound, light, and body

Shifting Seasonal Feel in Summer
May 5 (Rikka) in the modern calendar still feels like a continuation of spring. Sakura is falling; azalea and wisteria are blooming; the temperature is comfortable. We feel “summer” only from mid-June on.
August 8 (Risshū) in the modern calendar feels in the midst of high summer. Fierce heat, heatstroke, Bon vacation — one cannot call this “autumn.”
To reconcile this gap, modern poets:
- Compose Rikka through the end of May as “early summer” (shoka)
- Compose June-July as “rainy season” (tsuyu) or “high summer”
- Compose August as “late summer” (past Risshū if still hot) or as “residual heat” (zansho, an autumn kigo)
The gap between saijiki categories and modern feel is one of the important issues in modern haiku.
Toward the Next Article
From the heat and vigor of summer to the clear air and pensiveness of autumn. The next article steps into the world of autumn kigo — moon, autumn leaves, saury, cosmos, scarecrow, rice harvest. Autumn is the season with haikai’s most introspective feeling, and its masterpieces rival those of spring.
