Japan has released more video clips online that criticize Korea's efforts to promote the use of the name "East Sea" for the body of water between the two countries.
Tokyo's Foreign Ministry uploaded a series of six-minute-long promotional videos earlier this month in seven more languages,.. claiming the name "Sea of Japan" is the globally established title.
The videos posted on YouTube contain the same claim made in clips released last year in Korean, Japanese and English.
The two countries have been at loggerheads over the name of the sea for decades. Korean maps designate the waters the "East Sea" as it is a much older name than the "Sea of Japan" which Tokyo created in the early 20th century during its colonial rule of Korea.
