Abstract

Urban heating island effect (UHI) becomes a global serious problem these days, which should be caught attention to try to reduce it. Tokyo is one of the countries which faced this curious circumstance. The urban area of Tokyo had higher average temperature than rural area. The main reasons include too many high-rises and the materials in buildings which could increase the temperature. This article discuss the practical solutions for UHI in Tokyo and other countries.
