Villain from hand is very tight player from Japan - 15 vpip, 12 pfr, 5% 3bet after 900 hands

Flop - I shouldnt have there any raising range so 100% call.
Turn -I would usually bet AQ, but RNG said 100 so checkback
River - after using some timebank villain decided to shove over 300% of pot. Do you call there with your top rangeor just fold exploitatively? I don't expect to find over 43% of bluffs in his range.
