Wakashima Kyūzaburō (若島 久三郎, September, 1842 – January 6, 1891) was a Japanese professional sumo wrestler from Aizu, Mutsu Province (now Aizuwakamatsu, Fukushima Prefecture).

[4] He was a wrestler known for his pushing and thrusting techniques (tsuki/oshi),[2] but he rose slowly up the rankings, probably due to his cautious wrestling style.

[5] Shortly before his promotion to the jūryō division, he had to leave the Sumo Association briefly to serve in the Boshin War, alongside the Aizu Domain.

After this promotion, he quickly blossomed, and reached the status of san'yaku barely four years after his debut in this division,[5] winning the equivalent of two tournaments in the process.

In the January 1881 tournament, Wakashima faced Umegatani, who was then a dominant ōzeki, recording a winning streak of 58 consecutive victories.
