• Taste and Quality: The water in Sapporo is sourced from pristine rivers, lakes, and underground springs in the surrounding Hokkaido region. It is known for its soft water quality, which is gentle on the stomach and has a pleasant taste.
• Chlorination: Like most of Japan, Sapporo’s water is chlorinated to ensure safety. While the chlorine levels are low and within safe limits, some people may notice a slight chlorine taste or smell.

2. Sources of Water

• Primary Sources: Sapporo’s water supply comes from the Toyohira River, Sapporo Lake, and other nearby water bodies. These sources are regularly monitored for pollutants and contaminants.
• Filtration and Treatment: The city employs advanced filtration and treatment processes, including sedimentation, filtration, and disinfection, to ensure the water is free from harmful bacteria, viruses, and chemicals.

3. Filtration Practices

• Home Filtration: While tap water is safe, many residents and immigrants use additional home filtration systems (e.g., activated carbon filters) to improve taste and remove residual chlorine.
• Bottled Water: Bottled water is widely available in supermarkets and convenience stores for those who prefer it. Local brands often source water from Hokkaido’s natural springs.

4. Costs

Air Quality in Sapporo

1. General Air Quality

• Clean Air: Sapporo enjoys relatively clean air compared to other major cities in Japan, thanks to its location in Hokkaido, which is less industrialized and has abundant green spaces.
• Air Quality Index (AQI): The AQI in Sapporo typically ranges from 10 to 50 (Good), indicating low levels of air pollution. This is significantly better than in larger cities like Tokyo or Osaka.

2. Seasonal Environmental Factors

• Winter (December–March): Sapporo experiences heavy snowfall during winter, which can temporarily improve air quality by trapping airborne particles. However, heating systems and snow removal equipment may contribute to localized emissions.

• Summer (June–August): Air quality remains good, with minimal industrial pollution. However, occasional agricultural activities in rural areas may cause slight increases in particulate matter.
• Autumn (September–November): Air quality is excellent during autumn, with cool, crisp air and minimal allergens.

3. Sources of Air Pollution

• Local Sources: The primary sources of air pollution in Sapporo are vehicle emissions, heating systems during winter, and occasional construction activities.
• Transboundary Pollution: On rare occasions, Sapporo may experience slight air quality degradation due to transboundary pollution from mainland Asia, particularly during spring.

4. Costs

• Air Purifiers: While not essential, some residents invest in air purifiers to reduce allergens and improve indoor air quality. Prices range from ¥10,000–¥50,000 depending on the model.

5. Public Facilities

• Green Spaces: Sapporo has numerous parks and green spaces, such as Odori Park and Maruyama Park, which contribute to cleaner air and provide residents with areas to relax and exercise.
• Public Transportation: The city’s efficient public transportation system (subways, buses, and trains) helps reduce vehicle emissions and maintain air quality.
