She then lost to French Open champion Francesca Schiavone in the third round 6-3, 6-3. Later on that same week, she went to China to participate at the China Open. She beat Anabel Medina Garrigues in the first round, but lost to Elena Dementieva in the second round, in three sets. Kimiko then returned home to compete at the HP Open in Osaka, Japan. Seeded sixth, she defeated teenage qualifier Laura Robson in the first round and compatriot Aiko Nakamura. In the quarterfinals, she upset top seed and world No. 8, Samantha Stosur (becoming the first 40-something player to win a match against a top-10 player) to book a semifinal encounter with third seed Shahar Pe'er.

This was the fifth consecutive calendar year she finished in the top 100 (and 11th overall).
In the round of 16 at Brisbane International, Date-Krumm pushed Dominika Cibulková (who would become a 2014 Australian Open finalist) to three sets.

Date played just one match in 2016, at the Australian Open, where she lost to Amandine Hesse. Shortly after the tournament, she announced that she would be undergoing surgery on her left knee, after an MRI scan revealed that a crack in the knee had become a rupture. It was also reported that her meniscus was badly worn out.
Date rejected the assumption that she would retire after her injury, stating "I didn't want to just quit because I was hurt. I used it as motivation." At 46 years of age, Date played her first match in over a year at the Kangaroo Cup. Awarded a wildcard entry into the main draw, she lost to eventual runner-up Zhu Lin 2-6, 2-6. She then won three qualifying matches for a tournament in Changwon, but lost in the first round to Park So-hyun. Her next match was not until several months later, in July, at the Stockton Challenger event; she was again defeated in the first round, losing 6-4, 3-6, 0-6 to Usue Maitane Arconada.
Date announced that she would retire after the Japan Open, saying that she had been troubled with ongoing knee and shoulder pain. In the first round, she was defeated 6-0, 6-0 by Aleksandra Kruni?.
Date played with short backswings on both forehand and backhand sides. Date's playstyle is representative of those that dominated during her first career in the 1990s using less topspin in favour of a flatter shot. She is considered to possess the most notable "pancake" forehand in the women's game, with one of the lowest average spin RPM ever. She relies on her opponent's power to hit sharp angles and catch her opponents off-guard.
Since her comeback, Date played the best on grass, and her style was once described as "all stealthy, neat athleticism".
Date was born in Kyoto, Japan. Her father is Juichi (died in 2007) and her mother is Masako. She has two siblings: Ryusuke and Junko. Date first played tennis at the age of six. She is left-handed, but was trained to play right-handed to follow Japanese custom. She was the tennis champion at Sonoda Gakuen Junior High School & Senior High School, where she graduated in 1989.
She currently owns and runs a German bakery in Tokyo named Frau Krumm.
