If you able to read Japanese, purchase from e-plus or Ticket Pia is quick and convenient way but if you feel too tough, here is the tips.

* Credit card issued not in Japan is normally not accepted at these ticket agency
*Ticket is normally divided in 3-5 category(S-D), S is most expensive.

1) Japanese Orchestra’s performance
If you willing to see Japanese orchestra,  contacting each orchestra‘s ticket office is the best way since normally they are organizing the concert and issuing tickets by themselves, so they probably have best choice for seating. They normally accepts phone and email for ticket purchase.

As you may know sometimes English acceptance here is not perfect, I suggest you to write them via email to avoid any misunderstandings. Normally they will ask you to pick up ticket at the venue 3omin prior to the concert begins. Paying by JPY cash is safest, if you prefer to pay by credit card, ask them first with showing which card brand you would like to.

2) Foreign Artists or Orchestra
If you have specific concert of inbound non-Japanese musician in your mind, best way is contacts promoter directly(First you should check who is inviting your artist in mind). They will tell you how to.

3) Other Choice
You can just go to the venue and ask for tickets at the ticket box but not recommended since its priory of ticketing is not top(Organizer is top priority), you may feel hard to communicate with English to the person at ticket box. However, if you would like to choose from various option or have question, you can just walk in, they may work hard for you.

Or if you find attracting concert at hall’s website, you can write to them and ask how to buy.
