we are going to Tokyo by night bus. We want to send luggage to Tokyo. It is strongly recommended that you pack lightly.
https://www.japan-guide.com/e/e2274.htmlDepending on bus operators and types of bus cars,
maybe you can have one luggage piece per person kept in the trunk room of your overnight bus.
(Please pay attention to the upper limits of size and weight.)
When you find a hotel which has rooms suitable for you 12 travelers,
it is worth asking the hotel staff whether they can receive your luggage and keep it until you appear.
Delivery might be delayed due to crowdedness during a busy season, congestion of the road traffic and bad weather conditions.
I recommend you get ready to collect your luggage on the day following the expected delivery day.
Can we drop our luggage to any nearby combini for takkyubin service? Unfortunately the answer seems to be: No, unless someone who lives in Japan can receive it.
In order to pick up your TA-Q-BIN parcel at a certain shop of convenience store, you have to join Kuroneko Members; in order to gain the membership, you have to register your address in Japan.
You can send your luggage by TA-Q-BIN to Yoyogi-Kita TA-Q-BIN Center,
which is near Busta Shinjuku and open from 8:00 to 21:00 on weekdays.
(The width + the depth + the height should be within 160 cm; the weight should be up to 25 kg.)
(YAMATO-BIN, which is capable of larger or heavier luggage pieces, cannot be combined with this center pick-up service.)
Busta Shinjuku is in front of New South Gate of (JR) Shinjuku Station, which is around the boundary of Shinjuku City and Shibuya City.
Both the highway bus arrival concourse and the taxi stand are on the 3rd floor.
You can walk or take a taxi to this TA-Q-BIN Center.

When you are in any of the following situations, it sounds better to send your luggage by Yu-Pack postal service to a post office which has an out-of-hours window.
(The width + the depth + the height should be within 170 cm; the weight should be up to 30 kg.)
: Your bus arrives on a Saturday, a Sunday or a public holiday.
: Your bus arrives in the very early morning.
: Your bus arrives to a stop near Tokyo Station.
In this case, even the nearest post office (which has such a window) may be too far away to walk to; it would be better to prepare cash for your taxi fare(s).
