The goal of this clinical trial is to test in Japanese adults who experience concerns regarding urinary frequency. The main question it aims to answer is: •Does consumption of Cranberry Phospholipids reduce daytime urinary frequency? Participants will be given the following tasks: * Take two tablets daily containing Cranberry Phospholipid for eight weeks. * Answer the questionnaire on the overactive bladder (OAB)-specific quality of life (QOL). * Answer the questionnaire on OAB symptoms. * Answer the questionnaire on urinary frequency during the study period. Researchers will compare Cranberry Phospholipids and placebo groups to see if Cranberry Phospholipids reduces daytime urinary frequency.

RECRUITINGMeasured value for the Overactive Bladder Questionnaire (OAB-q) questionnaire item "frequent urination during the daytime hours" after the 8-week intervention
Using OAB-q, we evaluate OAB-specific quality of life (QOL). The questionnaire have 33 items, including 8 items measuring "symptom bother" and 25 items measuring "impact on QOL," with each item rated on a 6-point scale."Impact on QOL" is scored across four domains: "Coping" (8 items), "Concern" (7 items), "Sleep" (5 items), and "Social Interaction" (5 items). Scores are calculated on a scale of 0 to 100, with higher scores indicating a greater degree of difficulty. On the other hand, the "impact on QOL" indicates that the higher the score, the better the QOL.
Time frame: After the 8-week intervention
Individuals whose the response to the OAB-q questionnaire item "frequent urination during the daytime hours" improved by one or more scale points after the 8-week intervention compared to Baseline
Using OAB-q, we evaluate OAB-specific QOL. The questionnaire have 33 items, including 8 items measuring "symptom bother" and 25 items measuring "impact on QOL," with each item rated on a 6-point scale."Impact on QOL" is scored across four domains: "Coping" (8 items), "Concern" (7 items), "Sleep" (5 items), and "Social Interaction" (5 items).

Time frame: Baseline, and after the 8-week intervention

Time frame: Baseline, after the 1-week intervention, the 3-week intervention and the 8-week intervention
The measured values, amount of changes, and percentage of changes from Baseline for all other questionnaire items of the OAB-q, excluding "frequent urination during the daytime hours," after the 8-week intervention

Time frame: Baseline, after the 1-week intervention, the 3-week intervention and the 8-week intervention
The measured values, and amount of changes and percentage of changes from Period 1 for the average frequency of urination during the daytime, during the nighttime, and all day, as measured during Periods 2 to 9
Participants will maintain a daily diary of their urination frequency during two distinct periods: for 7 days immediately preceding the Baseline, and from the beginning of the intervention until the day before the final examination.
Time frame: Period 1 (7 days prior to Baseline), Period 2~9 (periods separated by 7 days from the start of intervention)
Individuals who experienced adverse events
During the trial period, if a participant exhibits any clinically significant "new manifestation of abnormality" or "aggravation" in his/her physical signs and symptoms, it is considered to be an adverse event.
Time frame: After the 8-week intervention
Individuals whose values of urinalysis and peripheral blood test are outside the reference range after intervention despite within the reference range at Baseline
The ratio of cases which had test items stated in urinalysis and peripheral blood examination within their respective standard ranges before intervention but exceeded the ranges after intervention are calculated, intergroup comparison at each time point is performed using tests for comparing proportions.
Time frame: Baseline, and after the 8-week intervention
Body height
Body height is measured using a height meter.
Time frame: Baseline, and after the 8-week intervention
Body weight
Body weight is measured using a body scale.
Time frame: Baseline, and after the 8-week intervention
Blood pressure
Systolic and diastolic blood pressure are measured using a digital wrist-type sphygmomanometer.
Time frame: Baseline, and after the 8-week intervention
Urinalysis
A urine sample (approximately 10 mL) will be collected from each participant, and the samples will be sent to LSI Medience Corporation for analysis.
