2.6 Contract Term

Standard Service]
[For monthly subscription]

• Fees will be incurred from the date of commencement of use of the Service as stipulated in the Terms of Service.
• The usage fee for the current month will be determined according to the file management capacity actually used by the customer at the end of each month (hereinafter referred to as "used file management capacity").
• If the Service start date is in the middle of a month, the usage fee for the month in question will be calculated on a pro-rata basis.
  • Usage fee for the month = Monthly usage fee - (Monthly usage fee x number of days not used / number of calendar days)
    * "Number of days not used" is the number of days from the first day of the month to the day before the Service start date.
    The pro-rata calculation is performed by multiplying first and dividing second, and rounding off the decimal point.
  【Example】
  In case of starting usage on January 16, 2026
  
  January 16, 2026 - January 31, 2026 (for 16 days)
  = {30,000 yen - (30,000 yen x 15 days / 31 days)}
  = 15,484 yen (excluding tax)
• Even in the event of termination of the subscription agreement in the middle of the subscription period in accordance with the provisions of the Terms of Service, the subscription fee for the month including the date of termination shall not be reduced or refunded on a pro-rata basis, but the full amount of the subscription fee for the relevant month calculated in accordance with the above shall be paid.

［In the case of an annual subscription]

• Fees shall accrue from the date of commencement of use of the Service as set forth in the Terms of Service.
• If the start date of this service is the first day of the month, the initial contract period will be one year from the start date of this service, and the initial fee will be the amount specified as the annual usage fee.
  Example]
  If you start using the service on January 1, 2026, the initial contract period will be from January 1, 2026 to December 31 of the same year, and the initial usage fee will be 360,000 yen (excluding tax), which is the annual usage fee.
  
• If the Service start date is in the middle of a month, the initial subscription period shall be from the Service start date to the end of the month that includes the date one year after the Service start date, and the initial usage fee shall be the monthly usage fee calculated on a daily basis (the calculation method is the same as that for the monthly subscription on a daily basis) for the month that includes the relevant service start date, plus the annual fee. The initial fee will be the amount obtained by adding the monthly fee (calculated on a pro-rata basis (the calculation method is the same as the pro-rata calculation method for monthly subscriptions)) to the annual fee.
  Example]
  If you start using the service on January 16, 2026, the initial contract period will be from January 16, 2026 to January 31, 2027, and the initial usage fee will be as follows.
  
  ① From January 16, 2026 to January 31, 2026 (for 16 days)
  = {Monthly fee - (Monthly fee x number of days not used / number of calendar days)}
  = {30,000 yen - (30,000 yen x 15 days / 31 days)}
  = 15,484 yen (excluding tax)
  
  ② From February 1, 2026 to January 31, 2027 (for 12 months)
  = annual fee
  = ¥360,000 (excluding tax)
  
  Therefore, the first fee = (1) + (2) = ¥375,484 (excluding tax)
• The subscription period for the second and subsequent subscription periods is one year from the day following the expiration date of the previous subscription period, and the usage fee for the next subscription period will be determined based on the usage file management capacity as of the end of the month preceding the month in which the current subscription period expires (hereinafter referred to as the "expiration month"). If the file management capacity used exceeds the maximum file management capacity (100 GB) available at the annual fee, the customer will be required to pay in a lump sum the annual fee plus the monthly excess usage fee (5,000 yen (excluding tax) per month per 100 GB) for 12 months in proportion to the excess capacity. The maximum available file management capacity will be increased by the amount of the excess usage fee paid for the next contract period.
  Example]
  If the current contract term is from January 1, 2026 to December 31, 2026, and the file management capacity in use is 450GB as of the end of November 2026, the monthly excess usage fee will be 20,000 yen (excluding tax) since the excess capacity is 350GB.
  The monthly excess usage fee will be 20,000 yen (excluding tax) since the excess capacity is 350GB. Therefore, the usage fee for the next contract period (from January 1, 2027 to December 31, 2027) will be 600,000 yen (excluding tax), which is the annual fee of 360,000 yen (excluding tax) plus 240,000 yen (excluding tax) for 12 months of 20,000 yen (excluding tax). As a result, the maximum available file management capacity will increase from 100GB to 400GB to 500GB for the next contract period only (from January 1, 2027 to December 31, 2027).
• During the contract period, we will check the file management capacity used at the end of each month. If the file management capacity exceeds the maximum file management capacity available at that time, the monthly overage charge (5,000 yen (excluding tax)/100GB per month) will be determined according to the excess capacity, and the monthly overage charge multiplied by the number of months from the month of excess to the expiration month of the contract period will be charged in a lump sum. The same shall apply thereafter. The maximum file management capacity will be increased by the amount of the excess usage fee paid for the period from the month of the excess to the month of the expiration of the contract term.
  If, at the end of the month in which the subscription expires, the file management capacity used exceeds the maximum file management capacity available at that time, the monthly excess usage fee (5,000 yen (excluding tax) per 100 GB per month) for the month in which the excess capacity is used will be determined according to the excess capacity, and the monthly excess usage fee for the current subscription period will be paid as the excess usage fee. In addition, the monthly excess usage fee for the next contract period shall be paid in a lump sum for 12 months (as described in (4) above, since the usage fee for the next contract period has already been determined and paid as of the last day of the month prior to the expiration month of the contract period, the excess usage fee for the next contract period shall be paid in a lump sum for the next contract period). (As stated in (4) above, since the usage fee for the next contract period has already been determined and paid at the end of the month prior to the expiration month, any excess usage fees discovered at the end of the expiration month will be paid at this time as additional usage fees for the next contract period). (Since the excess fee is already paid on the last day of the month in which the contract expires, you will be asked to pay the additional fee for the next contract period at this time.
  Example 1]
  If your file management capacity exceeds the maximum file management capacity available at the end of the month prior to the month in which your contract expires
  
  If your file management capacity is 250 GB as of the end of February 2026 and the maximum file management capacity available at the end of February 2026 under the current annual contract from January 1, 2026 to December 31, 2026. If the maximum available file management capacity is 100GB as of the end of February 2026, and the excess capacity is 150GB, the monthly excess usage fee for the month of February will be 10,000 yen (excluding tax), and the monthly excess usage fee of 110,000 yen (excluding tax), which is 10,000 yen (excluding tax) multiplied by 11 months from February to December, will be paid in a lump sum. The monthly fee will be 10,000 yen (excluding tax) multiplied by 11 months from February to December. As a result, the maximum available file management capacity will increase from 100GB to 200GB to 300GB for the period from February to December 2026.
  
  Furthermore, if the maximum file management capacity available as of the end of April 2026 is 320 GB, the excess capacity will be 20 GB because the maximum file management capacity available as of the same date is 300 GB, and the monthly excess usage fee for April, the month of the excess, will be 5,000 yen (excluding tax), and the monthly excess usage fee will be 5,000 yen (excluding tax) for the month of the excess. The monthly fee of 5,000 yen (excluding tax) multiplied by nine months from April to December will be 45,000 yen (excluding tax), which will be paid in a lump sum. The maximum available file management capacity will be increased by 100 GB from 300 GB to 400 GB for the period from April to December 2026.
  Example 2]
  If the used file management capacity exceeds the maximum file management capacity available at the end of the month in which the contract term expires
  
  If the used file management capacity is 320GB at the end of December 2026 under the current annual subscription contract from January 1, 2026 to December 31 of the same year, and the If the maximum file management capacity available is 300GB, the excess capacity is 20GB, so the monthly excess usage fee for the excess month of December will be 5,000 yen (excluding tax), and the monthly excess usage fee for the next contract period will be 5,000 yen (excluding tax) for the current contract period, plus 5,000 yen (excluding tax) for the next contract period, for a total of 12 months. The new fee is 65,000 yen (excluding tax), which is the sum of 5,000 yen (excluding tax) for the current contract period and 60,000 yen (excluding tax) for 12 months of 5,000 yen (excluding tax) per month as the excess usage fee for the next contract period, payable in a lump sum. As a result, the maximum available file management capacity will increase by 100 GB from 300 GB to 400 GB for December 2026 and the next contract period (from January 2027 to December 2027) only.
• Even if the subscription is terminated in the middle of the contract period in accordance with the Terms of Service, the annual fee will not be reduced or refunded on a pro-rata basis, and the full amount of the annual fee calculated in accordance with the above will be due and payable.
