Theme park sweethearts Takumi Hashimoto and Azumi Matsuzawa, took the plunge on the top of the world's steepest rollercoaster as they celebrated their first wedding anniversary on Sunday.
The Takabisha, is located in Yamanashi Prefecture at the base of Mount Fuji.
The couple tied the knot last year on April 1st, but Hashimoto did not properly propose, something he admits he should have done a long time ago.
The 31-year-old said: "I've been waiting for this opportunity and today I will do it there."
So, as the couple reached the ascent to the highest point of the roller coaster, Hashimoto shouted:
"Azumi! I apologize for making you wait so long for me to pop the question, but will you marry me?"
Unsurprisingly, Azumi replied, "Yes, I will!"
Then the couple shot down the drop screaming as family and friends shouted and clapped from below.
The Takabisha holds the Guinness Book of World Records for steepest roller coaster drop with an angle of 121 degrees at the beginning of the 160 second ride and reaches speeds of up to 100 km/h.
