Core Viewpoint - The article discusses the evolution of consumer society in Japan, as analyzed by sociologist Minoru Miura in "The Fourth Consumption Era," highlighting the shift from material wealth to social connections and meaningful consumption [2][10]. Group 1: Four Stages of Consumer Society - The development of Japan's modern consumer society is divided into four stages: 1. First Consumption Era (1912-1941): Characterized by industrialization and consumption limited to the wealthy, focusing on Western lifestyle and goods [4]. 2. Second Consumption Era (1945-1974): Post-war economic growth led to mass consumption, with a focus on essential appliances known as the "three sacred treasures" (TV, washing machine, refrigerator) [4][7]. 3. Third Consumption Era (1975-2004): Transition from quantity to quality in consumption, with an awakening of brand consciousness and a shift towards personalized and differentiated needs [4][7]. 4. Fourth Consumption Era (2005-2034): Emphasis on social connections and meaningful living, moving from materialism to a focus on sustainability and human relationships [5][7]. Group 2: Transition from High Consumption Society to Fourth Consumption Era - The transition from the third to the fourth consumption society is marked by five key characteristics: 1. Shift from individualism to social consciousness, moving from self-interest to altruism [11]. 2. Transition from private ownership to a sharing mindset [11]. 3. Change from brand obsession to a preference for simplicity and leisure [11]. 4. Movement from a focus on Western ideals to a greater appreciation for local and national identity [11]. 5. Realization of the shift from material goods to service-oriented consumption, emphasizing human connections [11]. Group 3: Changing Perspectives on Consumption - As society matures, the demand for material goods diminishes while the desire for fulfilling interpersonal relationships increases, indicating a shift in how consumption is perceived [13]. - Consumption is viewed as a means to enrich life experiences rather than merely a transactional activity, emphasizing the importance of time and relationships over material accumulation [13].
