In an effort to make summer rail travel less intense, JR Tokai has introduced a 'soft cooling' car to their Shinkansen bullet trains. For passengers who might be sensitive to extreme air conditioning, these new coaches with a weaker cooling system will provide a more comfortable journey. The move comes as the company aims to address varied passenger comfort settings during the hot and humid Japanese summer.

As a country with a robust rail transportation network, especially in bullet trains or Shinkansen, comfort and convenience of passengers is a high priority in Japan. Summer weather can be particularly hot and humid, thus air conditioning is necessary. However, varying cooling preferences necessitated the introduction of a different cooling option. Aside from comfort, this also reflects Japan's attention to details especially in service industries.

In the US or EU, issues concerning public transport comfort are also addressed but more often from the bigger picture like delays and accessibility. Unlike in Japan, there tends to be less focus on the minute details and more emphasis on broader comfort and convenience matters.
