Table schema:
CREATE TABLE constructorstandings (constructorid VARCHAR, points VARCHAR); CREATE TABLE constructors (name VARCHAR, constructorid VARCHAR, nationality VARCHAR)

Question: Find the names of Japanese constructors that have once earned more than 5 points?
SQL: SELECT T1.name FROM constructors AS T1 JOIN constructorstandings AS T2 ON T1.constructorid = T2.constructorid WHERE T1.nationality = "Japanese" AND T2.points > 5
