Tokyo is launching a dating app where users have to verify their income and promise they want to get married, as Japan fights tumbling birth rates

• The government of Tokyo is launching an app to help its citizens find love — and get married.
• Japan is experiencing record-low birth and marriage rates and the numbers are particularly bad in Tokyo.
• Elon Musk, who has called population decline a greater threat than climate change, tweeted his support for the app.

In February, Japan's government said "unprecedented steps" must be taken to tackle the country's record-low birth rates.
