When I use isalpha method with Japanese, I got it True whenever.

For example,

```
>>> "あいう".isalpha()
True
```

Is it the correct behavior?

Thanks for readning.

From the documentation: https://docs.python.org/3/library/stdtypes.html#str.isalpha

Alphabetic characters are those characters defined in the Unicode character database as “Letter”, i.e., those with general category property being one of “Lm”, “Lt”, “Lu”, “Ll”, or “Lo”.

I'm assuming those characters all have these properties.

That last line should have been "I'm assuming those characters all have one of these properties."

I'm going to close this issue. If you still think there's a bug here, you can let us know why and reopen this issue.

unicodedata.category can be used here I guess to validate this.

>>> [unicodedata.category(c) for c in "あいう"]
['Lo', 'Lo', 'Lo']
