SMAP Magazine is a good textbook for you to learn Japanese.
Welcome to Japan.
I want to sing SMAP songs with you in karaoke box.
May and October is good season for Japanese,
because of comfortable temperature.
We can enjoy flowers in May and
autumn color of leaves in October.
But sakura season around April Fool's Day or
snow season in winter may be better for Indonesians.
It is very difficult to get tickets of SMAP concert.
If you line up the ticket center for 12 hours,
you may get the ticket. Sorry.
The ticket center is almost many places in Japan. I don't know the ticket system recently, but it may be able to get tickets in telephone. I may try to get the ticket, but maybe it is impossible to get.
