Citizen sponsorship applications are now open for the 45th Yokohama Port Opening Festival, scheduled to be held on Monday, June 1 and Tuesday, June 2, 2026.
The Yokohama Port Opening Festival is a truly Yokohama-style event, supported every year by sponsorships from many local residents and companies. This year’s citizen sponsorship program includes not only original goods, but also return gifts such as viewing seats that can be used from around the evening of Tuesday, June 2.
One return gift that especially stands out is the special viewing seats that appear to offer an up-close view of the fireworks. As of now, the official fireworks program name and launch time have not yet been widely announced, but judging from the return gift details, it seems highly likely that a fireworks performance is planned for the evening of June 2.
Viewing seats that can be used from the evening of June 2 are available as return gifts for citizen sponsorship. That’s definitely something to keep an eye on!
If you want to see the fireworks up close, it may be worth checking the citizen sponsorship options instead of only waiting for regular ticket sales.
We’ve picked the best options for flights, transport, hotels, and activities — so you know exactly where to book.

What Is Citizen Sponsorship for the Yokohama Port Opening Festival?
Citizen sponsorship for the Yokohama Port Opening Festival is a sponsorship system designed to support the festival. Depending on the sponsorship amount, return gifts such as viewing seat tickets and original goods are available.
Rather than being a regular ticket sale, this system provides return gifts as a thank-you for supporting the Yokohama Port Opening Festival. For that reason, even if you are applying mainly for the viewing seats, it is important to check the official page in advance for details such as refund conditions and delivery timing.
The Highlight: Return Gifts That Appear to Include Fireworks Viewing Seats! Available from the Evening of June 2
What stands out most this time is the return gift that includes viewing seats available from around the evening of Tuesday, June 2.
On the official citizen sponsorship page, terrace seats in front of the National Convention Hall and special seaside viewing seats are listed as return gifts. Both are introduced as viewing seats available from around the evening of Tuesday, June 2, and they appear to be seats for enjoying the nighttime events of the Yokohama Port Opening Festival.
A major point is that the special seaside viewing seats are described as seats where visitors can watch the launch fireworks from near the base. The official fireworks time has yet to be announced, but it seems fair to say that the possibility of a fireworks performance on the night of June 2 is quite high.
Special Seaside Viewing Seats Are Available for Groups of 2 or 4
The special seaside viewing seats are available as 2-person seats and 4-person seats. The viewing area is described as being near the Shioiri-no-Ike pond, and these seats are likely to attract attention as a way to enjoy the fireworks from a very close location.
The sponsorship amount is 50,000 yen for a 2-person seat and 100,000 yen for a 4-person seat. In both cases, viewing seat tickets are sent as return gifts for sponsorship of the Yokohama Port Opening Festival.
For those who want to enjoy the night of the Yokohama Port Opening Festival from a special location with family or friends, this is definitely a return gift worth considering.
Terrace Seats in Front of the National Convention Hall Are Also Available from the Evening of June 2
The terrace seats in front of the National Convention Hall are listed as a return gift for a 25,000-yen sponsorship and are designed for two people. The description does not emphasize fireworks as strongly as the special seaside viewing seats, but since they are viewing seats available from around the evening of June 2, they can be understood as seats intended for enjoying the nighttime events and possibly the fireworks.
For those who want to enjoy the night of the Yokohama Port Opening Festival from reserved viewing seats while keeping the sponsorship amount lower than the special seaside viewing seats, this is also a return gift worth checking.
Stage-Front Viewing Seats and Original Goods Are Also Available as Return Gifts
The return gifts for citizen sponsorship are not limited to seats that appear to be for fireworks viewing. There are also viewing seats that let you enjoy the Yokohama Port Opening Festival from closer to the action, as well as original goods that make nice keepsakes.
Stage-front viewing seats are available as single-person seats in front of the main stage, and they can be used on both Monday, June 1 and Tuesday, June 2. Rather than being specifically for fireworks, it seems more natural to think of them as viewing seats for enjoying the stage events of the Yokohama Port Opening Festival up close.
Other return gifts listed include the Yokohama Port Opening Festival original towel, a plush toy set featuring Hama-kun and Yoko-chan, a Hama-kun plush toy, and a Yoko-chan plush toy. For those who are not considering viewing seats but still want to support the Yokohama Port Opening Festival, the goods-based return gifts may be easier to choose.
| Return Gift | Details | Sponsorship Amount |
|---|---|---|
| Stage-front viewing seat | Single-person seat in front of the main stage. Available on June 1 and June 2 | 10,000 yen |
| Terrace seats in front of the National Convention Hall | 2-person seats available from around the evening of June 2 | 25,000 yen |
| Special seaside viewing seats | Seats described as allowing visitors to watch the launch fireworks from near the base | 2-person seat 50,000 yen, 4-person seat 100,000 yen |
| Original towel | Yokohama Port Opening Festival original towel and other items | 2,000 yen |
| Plush toy set | Hama-kun and Yoko-chan plush toy set | 7,000 yen |
Important Points to Check Before Applying
If you apply for viewing seats as a return gift for citizen sponsorship, it is important to understand that this is slightly different from a typical event ticket purchase.
The official page explains that, due to the nature of sponsorship, refunds are not accepted. It also states that even if the Yokohama Port Opening Festival is canceled, the return gifts will still be shipped, but refunds cannot be made.
Return gifts are scheduled to be shipped sequentially from around mid-May before the Yokohama Port Opening Festival. Details such as the available time for using the viewing seats will be provided together with the delivery of the return gifts, so be sure to keep checking official announcements after applying.
The chance to see the fireworks from a good spot is appealing, but it’s important to understand that these seats are positioned as return gifts for sponsorship.
Before applying, make sure to check the official page for refund conditions, shipping timing, and details about when the seats can be used.
If You Want Fireworks Viewing Seats, Check the Citizen Sponsorship Page Early
For the 2026 Yokohama Port Opening Festival fireworks, we still need to wait for the official program name and launch time to be announced.
However, considering that viewing seats available from around the evening of Tuesday, June 2 are being offered as citizen sponsorship return gifts, and that the special seaside viewing seats are described as seats where visitors can watch the launch fireworks, the night of June 2 is likely to attract a lot of attention.
If you want to enjoy the Yokohama Port Opening Festival fireworks from a better spot, or if you prefer to avoid the crowds and watch in a more relaxed setting, it is recommended to check the citizen sponsorship return gifts early.
Can You Participate in Citizen Sponsorship Even If You Are Not a Yokohama Resident?
When you see the term citizen sponsorship, you may wonder whether it is only for Yokohama residents.
However, based on the official citizen sponsorship page, there does not appear to be any statement limiting participation to Yokohama residents. If you want to support the Yokohama Port Opening Festival, it seems possible to consider applying even if you live outside Yokohama.
In fact, the Yokohama Port Opening Festival is one of Yokohama’s signature events, visited not only by Yokohama residents but also by many tourists every year. For those outside the city who are looking forward to the festival, or for anyone who wants to watch the fireworks from reserved viewing seats, the citizen sponsorship return gifts are worth checking.
That said, because return gifts are shipped, be sure to check the official page for details such as the registered address, delivery method, and payment options when applying.
Can Foreign Nationals Participate in Citizen Sponsorship?
For foreign nationals as well, the official page does not appear to show any restrictions based on nationality.
Therefore, foreign residents in Japan or visitors who plan to stay in Japan around the time of the Yokohama Port Opening Festival may be able to consider applying if the conditions work for them.
On the other hand, since citizen sponsorship return gifts include the shipment of viewing seat tickets and goods, those living overseas should be careful before applying. It is best to check the official page in advance to confirm whether you can register an address where the return gifts can be received, whether your payment method can be used, and whether you can receive the necessary information for using the viewing seats on the day.
When explaining this to international visitors, it is safer not to say that anyone overseas can easily apply. Instead, it is better to say that it may be worth checking for those who have an address in Japan where they can receive the return gifts, or those who can confirm delivery arrangements at their accommodation.
If You Want to Enjoy the Fireworks More Comfortably, Restaurants and Hotels with Fireworks Views Are Also an Option
Even if the special seats allow you to watch the fireworks up close, viewing them outdoors in the humid early-summer weather might not be ideal for everyone.
If that sounds like you, why not look for a stylish restaurant or hotel in the Yokohama and Minato Mirai area where you can see the fireworks?
Although it has not yet been officially announced that fireworks will take place on June 2, some special plans are already available.
Even outside special plans, there are also restaurants and hotels where you may be able to get a good view of the fireworks.
We introduce them in the article below, so please use it as a reference!
