Nihonium is a period-113 oscillator, found by Jeremy Tan on July 5, 2021. It was the smallest known oscillator of its period until the discovery of 86P113 in October, 2022. It is an emu comprised of two R64 and two R49 conduits populated with two Herschels whose first natural gliders annihilate each other; both Herschels must be present for the oscillator to work, but one Herschel may be advanced in time to yield a period-226 oscillator, the least-populous of them at 107 cells called nihonium*.

A 52-glider synthesis was found for nihonium on the day of its discovery. On July 23, 2023, KtT reduced the synthesis cost from 50 gliders down to 49 gliders. On August 16, 2023, Chris857 reduced the synthesis cost down to 48 gliders.
