China has decided to hike Japan’s visa prices by approximately 7.5 times, a significant increase that could impact tourism and trade between the two countries. No clear reason for this sudden spike has been given yet. The news comes at a time when the countries' bilateral relations are experiencing uneasy moments.

The news has been met with sheer surprise among the Japanese, given the potential impacts on tourism, business travel, and overall relations between the two nations. Japan, known for its respect for international norms and good neighbor policy, could see this as a challenge to its diplomatic relations with China.

The US and EU have also faced similar issues, with occasional hikes in visa prices, usually variations reflecting international relations' ebb and flow. However, such a significant increase as Japan now faces is quite rare.
