1. Timeline & Typology: Early, Mid, Late Showa

Early Showa (1926–1945): Tradition Meets Western Influence

In the early Showa era, houses were still rooted in traditional Japanese architecture, with increasing Western influence. These houses often combined tatami rooms, sliding fusuma, shoji screens, and genkan entryways with Western‑style rooms.

Key Features:

• Tatami rooms (washitsu) as the heart of the home

• Fusuma (sliding doors) separating multi-use spaces

• Shoji screens that diffuse natural light

• Genkan (entryway) with raised flooring

• First appearance of Western-style rooms with hardwood floors

• Use of natural materials: wood, earth, clay, washi

Influences:

• Taisho-era romanticism

• Western architecture from Europe and the U.S.

• Rise of urban minka inspired designs

Mid-Showa (1945–1960): Post-War Recovery & Mass Housing

After WWII, Japan faced rapid population growth and material shortages. Housing during this period was simple, minimalistic, and functional. Houses in this period were often modest, utilitarian, with simple wooden construction or light structures.

Also, in this period, prefabricated (プレハブ) housing and panelized construction began to appear.

Key Features:

• Lightweight wooden structures (due to limited materials)

• Compact layouts with one or two tatami rooms

• DK (Dining Kitchen) layout appears

• Oshiire closets for folding and storing futons

• Separate bath and toilet becomes more common

• Exterior walls often corrugated metal or basic concrete

  
  

These homes were modest, affordable, and designed for families rebuilding their lives. Today, they evoke a strong sense of Showa nostalgia.

Late Showa (1960–1989): Economic Boom & Modernization

As Japan entered high economic growth and then the bubble era, homes became larger, built with more modern materials (RC, steel, concrete), and incorporated more Western‑style living spaces. This is when many of the iconic “Showa Retro” interior motifs were created.

Key Features:

• Concrete and steel construction

• Combination of Japanese-style rooms and Western-style living rooms

• Unit baths and improved kitchen systems

• Larger windows, aluminum frames

• Television-centered living areas

• Built-in cabinets and improved storage solutions

This is also when many iconic Showa Retro interiors emerged: patterned linoleum, warm-tone woods, and the unforgettable “Showa orange and brown” palette.
