Data Allowance:
Additional data bundles cannot be added to our Japan Voice+Data plans, so once you have exceeded your high speed data allowance, your connection speed will be restricted (to a maximum of approximately 200 Kbps) until your plan is reset and you are assigned a new high speed data allowance on the 1st of the following month.
If you find that you are regularly exceeding the high speed data allowance included with your plan however, you may wish to consider upgrading to an alternative ongoing plan with a larger data allowance.
