Hashimoto beat Muramatsu 6–5 in the final of the Japanese qualifying tournament for the 2014 World Championship. He saw off Paul Lim 4–2 in the preliminary round and won the opening set in his first round match against Michael Smith, but went on to lose 3–1. In June, Hashimoto and Muramatsu watched as Canada missed seven darts for the match in the first round of the World Cup of Darts to step in and steal a 5–4 win. In the second round they both lost their singles matches against the Northern Irish partnering of Brendan Dolan and Michael Mansell to exit the tournament. A year later, after whitewashing China 5–0, they were knocked out at the same stage this time by the top seeds England. Hashimoto lost 6–2 in the first round of the inaugural Japan Darts Masters to James Wade.
