Courtesy of Takuya of http://www.traicy.com/, he informed me Spring Airlines has a promotion for 1 Yen on the Japanese site, or $1.60 USD on the English site for flights between Shanghai and Saga, Japan.
While Spring Airlines advertises this as a sister airport to Fukuoka, it’s still about an hour away by train and at least 1180 yen fare, so keep that in mind.
Total on the English site came out to $165.60 USD roundtrip.
Total on the Japanese site came out to 12982円 roundtrip. About the same when converted.
I’ve covered Spring Airlines in my previous posts, it’s a budget airline based out of Shanghai with very competitive fares to various destinations, including Hong Kong!
