I'm getting confused about stroke order of some kana and kanji. When I was taking Japanese classes Sensei drilled us to write top to bottom left to right. I'm studying on my own now.
For ヒ one of my katakana books shows the horizontal stroke starting at the right and slanting slightly down to the left, then the bended stroke. Another book and some online animations show the bended stroke first then the horizontal line going left-to-right or right-to-left with or without the slant. Which is correct? What about ナ?
Same question with some Kanji that seem to break Sensei's top to bottom then left to right starting point rule. Example, my Kanji book stroke order for 七, 九, and 10 (can't find the key-combo for the Kanji) breaks this rule. 七 and 10 start with the horizontal stroke then the bended/vertical strokes. 九 shows the vertical stroke first then the horizontal bending one. So 七 and 10 are left to right top to bottom, and 九 is top to bottom left to right.
Other examples from the same book 水 starts with the vertical (top), 土 starts with the upper horizontal (left), 女 starts with the bended vertical (top).
My Kanji book is Basic Kanji published by Bonjjinsha and I recently have been skimming part of Heisig's Remembering the Kanji.
Is there some nuance to applying the top-down-left-right rule?
Thanks.
