When should I order?
Orders should be placed 2 to 3 days in advance. Expedited shipping is available for an additional fee. Please refer to our shipping map for regional delivery details.
Can I cancel my reservation?
Yes, you can cancel your order by contacting us via email. Cancellations made four or more days before your scheduled rental period are free of charge. For cancellations made three days or fewer before the start date, a ¥3,000 cancellation fee will apply. Please note that credit card transaction fees are non-refundable, and any differences in exchange rates will not be accounted for.
Why is there no optional add-on insurance policy?
As traveller’s insurance generally covers compensation fees, we believe an add-on insurance policy is not very beneficial to our customers. However, please check with your insurance agency/company beforehand to see if a travel insurance is provided or not. If you need to file a report to your insurance provider (e.g. credit card company), then please let us know as we would be happy to provide any necessary documents to do so.
Is there a fair usage policy?
After exceeding 1GB/day, there will be a capping of 200kbps unlimited data which refreshes at 0:00 AM JST (Japanese Standard Time). No pay-per-use additional fees will apply.
How much usage can I get out of 1GB?
Please refer to this graph.
Can I top-up my data usage?
Unfortunately, we do not provide top-up options with this plan.
Do extensions cost extra?
Extensions will not incur an extra fee for the extension, the customer will simply be charged the cost of the extra days. Note that extensions will need to be requested prior to the end of the initial requested service period.
