Shinkansen High Speed Rail, Singapore and Malaysia: $17 to $20 billion
The Shinkansen, the bullet train that connects Tokyo to other cities in central Japan, first opened in 1964. Though this iconic system remains the gold standard for high-speed rail travel, it's only in recent years that Japan has been successful in exporting it to other countries.

Japan will provide some of the funding as well as the technology, The Straits Times reported.

Tokyo 2045: TBD
