How we predicted this

Our honest method.

We look at every film released theatrically in the last 48 months across our 15 prediction markets that has SINCE made it to streaming. We compute how many days it took to go from theatrical to streaming for each one. That historical distribution gives us two reference deltas: a Japan-specific median (when we have enough local data) and an Asia-regional median (the much larger cross-country pool). We blend the two based on how many local samples we have for Japan.

For In the Grey in Japan flag Japan, the anchor is the theatrical release on August 21, 2026. Applying our blended model:

Method: country-median delta 92d, n=19, σ=64d
Sample size used: 19 comparable films in Japan
Confidence: MEDIUM

Confidence improves week over week as our cross-country training pool grows. Each weekly cron run adds more observed (theatrical → digital) deltas to our model.

We don't predict the SPECIFIC streaming service in v1 (Netflix vs Prime vs JioHotstar) because that requires studio-level data we don't yet have reliably. When the title actually arrives, we update this page with the real provider and your alert email goes out automatically.

Track record in Japan so far: 0% of our 14 confirmed arrivals landed inside the window we published. Every confirmation, hit or miss, stays on the record.
