I think that the problem is based on 'font search'. 
You wrote

So, probably some texts to display are Japanese, aren't it? 

Many of(?) TrueType fonts on Windows have both of Japanese and English 
Glyph. But on X, Font files are separated by encoding. If you configure 
the font to 'Helvetica', Tk will search Japanese 'Helvetica' font to 
display Japanese text, and if you configure the font to 'Mincho', Tk 
will search English 'Mincho' font to display English text. But most of 
X environment will have no Japanese 'Helvetica' font or no English 
'Mincho' font. Therefore, Tk must search another font instead of the 
right font, and it will need long time.

Please define font aliases for Japanese 'Helvetica' font and so on. 
You will be able to get a little faster start up.
