* Healthy Japanese male subjects,
* Aged 20 to 40 years inclusive.
* Subjects without signs of skin irritation (erythema,dryness, roughness or scaling) on test sites.
* Subjects willing to follow the study procedures and complete the study Subjects having understood and signed a written informed consent.
* Subjects without abnormal in physiological test and clinical test in screening, and also judged as possible to participant the study by investigators.

Exclusion Criteria:

* History of alcohol, chemical or drug abuse
* History of allergic reaction to drugs or history of skin reaction to the tape
* Any systemic or cutaneous disease that could in any way confound interpretation of the study results (e.g. atopic dermatitis, eczema, psoriasis)
* Known sensitivity to any component of any of the formulations being tested
* Known hepatic or renal disorders
* Use of systemic, locally injected or inhaled corticosteroids within 4 weeks of study start (Day 1)
* Use of systemic vitamin D analogues, vitamin D or calcium supplements within 4 weeks of study start(Day 1)
* Use of any drug (systemic or topical) within 2 weeks of study start (Day 1)
* Use of non-marketed/other investigational products one month prior to or 5 half lives (for those the half life is longer than one month) and during the trial is not permitted
* Any abnormality found at medical interview before administration of the test drug, which will affect the clinical study as judged by the investigator
* History of or active photo-induced or photoaggravated disease (abnormal response to the sun light)
* Exposure to excessive or chronic ultraviolet (UV)radiation (i.e., sunbathing, tanning salon use, phototherapy)within four weeks prior to inclusion (Day 1) or planned during the study period
* Scars, moles, sunburn, or other blemishes in the test area which would interfere with grading
