Hatsu Arashi Japanese Morning Glory does NOT have Variegated leaves. They are a Solid Green Tri-Lobed.

There is, however, another Japanese Morning Glory that looks almost exactly like Hatsu Arashi that is Akatsuki no Umi and this JMG 'DOES' have Variegated Leaves

This beautiful creeper grows perhaps too well in the cooler regions of Australia. I live in Victoria, Australia and planted one cutting along a fence about five years ago. It has spanned about 10 metres and roots everywhere that it touches soil.....where it takes off again.
It is very beautiful, but is threatening to strangle everything in it's way. My husband is very unamused as he has been fighting this plant for about four years and it is still winning.

Lovely morning glory; almost the first to bloom in my yard this (early) summer. Not many of my seeds germ. but about 5 did and tho the vine is anorexic, it grew 7' and there are 3-8 blooms each day. Some near ground; some over the wall. A wonderful deep-dark blue. One of my favorites. Next year I'll plant about 50 seeds rather than 15 or 16. Got morning shade; afternoon sun. Maybe that's what stunted the vine a bit. Wonderul flower!!

A lovely bloomer - one of the first to open in my garden's this year. Grows well in part shade and seems to have a deeper color in shade rather than a little washed out if in full sun. A definite if you like "blues" in the garden.
