None of which change stock prices without money actually flowing into the stock market. Your own link said money was flowing from outside Japan into the Japanese markets, something that first requires these people to buy yen.
I am not denying that hot foreign money has been front running the BOJ in the Nikkei, in fact as you point out, I told you that. However you still seem to be laboring under the false premise that traders cannot simultaneously short Yen and bet on a rising Nikkei. Quaint old assumptions, but incorrect. If as you seem to think, the Nikkei cannot move without people "first buying yen, to buy actual stocks in the Nikkei" ...?
Then perhaps you'd like to explain to me the precise mechanism by which with Japanese markets
closed (US open) if the Nikkei Futures plunges 1000pts from the cash markets close the day before, that the Nikkei
opens 1000pts down, with NO stocks having been bought or sold ?
Everybody who actually owned Japanese stocks the day before still owns them at the instant of open, no money has gone in or out of the closed markets, and yet they are priced differently from the day before now. interesting, huh?
Clue. you still seem to be missing the "
contracts" part of it. What
is traded is a "contract (or promise) to deliver" based upon ..ie
no currency, and
no stocks denominated in Yen.

Nikkei 225 futures and options on futures provide investors around the globe with an efficient way to access the opportunities of the Japanese equity market, one of the world’s largest markets today (in terms of market capitalization).
The contracts track the benchmark Nikkei 225 Stock Average, with futures offered in both yen- and U.S. dollar-denominated contracts, to better serve customers with portfolios of investments in those currencies.
Let's talk through how it
actually works to spare you any further confusion.
If I have a $10 million trading account and decide that I'm going to risk 10% of the account on frontrunning this gift from the BOJ back in January across 4 separate trades, so max $250k loss per trade.
My account (same as real life) allows up to 200:1 leverage, in this case I'm confident so I'm using the maximum allowed.
1. Nikkei - I'm going to allow a 500 point stop loss which would take me out at 9850 at a loss of $250k.
MARGIN REQUIREMENTS & LEVERAGE
The minimum margin requirement for most Forex pairs is
0.5% (200:1), this can be changed to 1% (100:1) or 0.25% (400:1). The minimum margin requirement for energies, metals, soft commodities and indices is usually 1% (100:1) and this can be changed to 2% (50:1) or
0.5% (200:1) via your account setting in the platform.
so 1000 contracts x 10350 =
$10,350,000 position.
margin required in trading account for this position = 1.0% of 10,350,000 =
$103,500. my Target Take Profit is 14000, (the position will automatically close at that point)
2. USDJPY 100 contracts long at 88.00. Stop loss at 85.00 (300 pips) equates to a -$250k loss.
(1 contract = $100,000) position size = $10million, margin requirements = 0.5% = $50,000
Target take profit = 100.00 exchange rate (automatically closed)
Repeat for trades 3 & 4. Then in early May all these trades hit their targets.
Nikkei trade closed 1000 contracts x 3650 points = $3.65 million profit.
USDJPY trade closed 100 contracts x 1200 pips = $1 million profit
Repeat trades 3 & 4 (for considerably more pips each profit than USDJPY but assume same profit)
This trading costs me $250k ($50k/$100k per trade) put aside as margin for $40 million's worth of exposure, and a potential $1 million total loss
Note I have put 3x as much ($) bearish betting on the Yen as the bullish long Nikkei position, and not once, did I "buy Yen" what I have done, is entered into contractual derivatives positions, with my broker, who
may or may not hedge off any excess exposure (ie any not covered by their internal books and opposing bets) with their interbank liquidity providers.
this is part of what is known as the "Shadow banking system" and which is not dealt with by (m)any traditional economists as far as I'm aware, but is the basis of your incorrect assumptions.
because I've just shown you how the most basic of retail traders on a standard brokerage platform can do
exactly what you said isn't possible.
One final question for you to ponder: Where did my $3.65 million (Nikkei) + $3 million FX profits actually come from? ie whose
dollars do I now have in my account, and have they ever been converted into Yen in any direction? (no)
