i was lucky to go to sagamiko. it's actually a resort but during cherry blossom season there is illumination done on small hill. On the day i visited, sakura was in full bloom (called mankai). i missed the mankai in tokyo but got to see it in sagamiko.
i prefer to take photos in daylight and am not confident about night time photography. but surprisingly these photos turned out really good.
hope you will like it. if you get a chance do visit sagamiko in spring.
PS - we played in mirror maze and it was so tough to get out that at one point we became restless and i was bit scared. ;)
