Bringing souvenirs from Japan to India

I am an Indian citizen. I bought some Japanese souvenirs and gifts (plushie, chopsticks, pearl necklace, Japanese fan, and some more) from various shopping sites. I now need to get them back to India. As far as I know and understand, I did not make any tax-free purchase. Nearly everything was purchased with a 10% tax (which might look stupid now!). What would be the procedure like for me while passing through the customs? Should I be engaging the customs in Japan or India, since I have zero practical experience for any of that. Please help (my flight is tomorrow morning). Thank You!

there is no regulation for exporting such items in Japan.
you need to ask your country about import tax. it depends on countries.
