7. Management of payment codes


This function is provided only for Tokyo Tech users.

A payment code is required to purchase TSUBAME points required for using paid services.


Payment codes are only required for the Group manager (Main). Payment codes applied by anyone other than the Group manager (Main) cannot be used. Students cannot manage payment codes other than the budgets for which they are responsible.

7.1. Payment code availability period

There is a billing deadline that depends on the budget category. We restrict new purchases of TSUBAME points close to the deadline to ensure the billing process (e.g., totaling) is completed in time.

If your budget category is other than Institutional Operating Expense Funds(法人運営費) or Donations for Education and Research(奨学寄附金), the payment code can only be used within a new billable period that satisfies the following criteria:

  • Is within a research period
  • Is before the date described below:
    • If the last billable date is set and is the last day of the month, the last day of the previous month prior to the last billable date.
    • If the last billable date is set and is not the last day of the month, the last day of the month two months before the last billable date.
    • If the last billable date is not set, the same date above calculated using the end of the research period instead.
  • Is before December 31st of every fiscal year


Regarding Institutional Operating Expense Funds and Donations for Education and Research, purchases of TSUBAME Points from January to March will be paid from the same budget for the following year.

7.2. Payment code expiration date

All payment codes will become invalid at the end of the fiscal year.

From mid-March, we will begin accepting applications for payment codes for the following fiscal year. Payment codes applied for in advance will be held until the start date of the next fiscal year, following approval by GSIC and the budget supervisor (required if the budget manager is different). The code will become available from the start date of the new fiscal year and can then be assigned to groups, used to purchase points, etc.

When applications for payment codes for the next fiscal year become available, a checkbox for the next fiscal year will appear at the year of use on the "New payment code application" screen. If you want to apply for a payment code for the following fiscal year in advance, click the checkbox.

7.3. New payment code application


Grants-in-Aid for Scientific Research(科研費) has four different budget codes for each category, and TSUBAME's computer usage fee is classified as "Others(その他)". (Correnponding to "Facility and equipment usage fee in the research organization(研究機関内の施設・設備使用料)" in the Table of expense categories shared by ministries and agencies(府省共通経費取扱区分表))
Please note that applications for payment codes for expenses other than "Others(その他)" will be rejected as an incorrect expense category.

The process for payment code application is as follows.

You can use the "Payment code control" screen by choosing "Manage payment code" from the side menu.

Click the "New payment code request" to show the "Request for payment code" screen.

The following items are to be completed:

After the application, the person in charge of GSIC will confirm the application contents and decide whether to approve or reject it.
