Takabisha record-breaking 121°, beyond-vertical drop. Once the car is released from the top of the hill, it hurtles back down towards the ground and enters a dive loop, an inline loop and finally the seventh inversion, an immelmann loop. The whole ride is over within 2 minutes. When "Takabisha" opened on 16 July 2011 it gained the Guinness World Record for the steepest roller coaster made from steel. It officially took the world record from Fraispertuis City's "Timber Drop" S&S Worldwide El Loco roller coaster, which had gained the record only two weeks earlier. "Timber Drop"'s record was set at 113.1°
MKM steel MKM steel MKM steel, an alloy containing nickel and aluminum, was developed in 1931 by the Japanese metallurgist Tokuhichi Mishima. While conducting research into the properties of nickel, Mishima discovered that a strongly magnetic steel could be created by adding aluminum to non-magnetic nickel steel. The developers claim MKM steel is tough and durable, inexpensive to produce, maintains strong magnetism when miniaturized and can produce a stable magnetic force in spite of temperature changes or vibration. MKM steel is similar to Alnico. MKM is an acronym for Mitsujima ka magnetic, 'Mitsujima ka' being the name of the inventor's childhood home.
