Can you elaborate a bit on the part between Softbank spending on India's uber drivers resulting in an increase of Japanese exports? Is it just that there is a desire for Japanese products in India, but not enough cash?
Softbank invests in Uber India pushing up automobile demand[1]. Indian drivers buy cars manufactured by Maruti Suzuki (54% market share [2]). Maruti Suzuki is a JV between an Indian company (Maruti) and Suzuki (Japan) where-in Maruti pays 6% of sales as royalty for design and other facilities. In addition, you have to realize that Japan exports $35b of auto parts and $101b of automobiles [4]. So any lever which pushes up sales of automobiles in any nation is bound to have an impact on exports.

In Indiranagar (a popular, hip neighbourhood in Bangalore), you might have to wait for an hour to get an Uber or Ola, on weekday mornings too! Hence a lot of people are using Yulu (India's Bird).
I can see that, at the margins, a company can spend money where it thinks it it can receive complimentary benefits. But this idea that you can spend your way into riches is a fallacy.
So, I think we agree on some things, mainly that Japan is printing money and Softbank is a beneficiary and is using that cash to spread around the tech industry. Cheap money. Except I think it will backfire, eventually.
