5 Yuan / 5 Yan Ta Chiang Bank / Dagiang Inxang, green

Ta Chiang Bank (大江銀行) was a regional bank operating under Japanese-sponsored administration in occupied China during the Second Sino-Japanese War. Notes issued under these puppet financial structures in 1944 were circulated as part of a deliberate economic strategy to displace Chinese Nationalist currency in occupied territories and extract local resources — the banks themselves often had minimal reserve backing and no meaningful monetary independence from the occupying military apparatus.

The Pick reference S3690 places this firmly in the specialized category of Chinese local and regional issues, where documentation remains incomplete and authentic surviving examples are genuinely uncommon.
