# How do I choose Japanese souvenirs? How long do Shiroi Koibito, Tokyo Banana and ROYCE' Nama Chocolate keep, and should I buy at the airport or a department store?

> Check the shelf life first, then the piece count. Shiroi Koibito 24 pcs (2,289 yen) has a manufacturer-stated shelf life of 120 days at room temperature, so it travels best for sharing; Tokyo Banana keeps only about 7 days, and ROYCE' Nama Chocolate needs refrigeration and keeps about a month, so buy those at the airport on your last day. Department store food halls and flagship shops have the widest selection, and major airports such as Haneda and New Chitose carry the main brands (prices are tax-included on each brand's official site as of October 2026).

## Three shelf-life tiers

| Shelf life (manufacturer-stated) | Examples | Best for |
| --- | --- | --- |
| 1 month or more | Shiroi Koibito 24 pcs (120 days), Shogoin hard yatsuhashi (90 days), Sugar Butter Sand Tree (40 days), Hato Sable (about 30 days) | Long trips; handing out slowly after you get home |
| About 2 weeks | Hagi no Tsuki (about 14 days guaranteed when shipped from the online shop), nama yatsuhashi "Hijiri" (12 days), Cha no Ka (about 15 days) | Buying in the last few days of your trip |
| About 1 week, or refrigerated | Tokyo Banana (about 7 days), Rokkatei Marusei Butter Sandwich (9–10 days), ROYCE' Nama Chocolate (refrigerated, 1 month) | Buying on your departure day and sharing as soon as you're home |

LeTAO's Double Fromage cheesecake ships frozen and must be eaten within 48 hours of thawing, and it's mostly cheese and cream, so enjoy it in Japan rather than taking it home.

## Choosing for sharing vs. gifting

- **For coworkers and classmates**: pick boxes with many individually wrapped pieces, such as Shiroi Koibito 24 pcs, hard yatsuhashi 24 pcs (packs of 3, 648 yen), or Tokyo Banana 8 pcs.
- **For family and older relatives**: gift boxes like Hato Sable in a tin or YOKU MOKU Cigare look polished. Local specialties such as Hagi no Tsuki or nama chocolate also make good conversation pieces.
- **For people who don't like sweets**: Kitakaro's Kaitaku Okaki (scallop-flavored rice crackers) or ROYCE' Potato Chip Chocolate.

## Airport, department store or station?

- **Department store food halls and flagship shops**: the widest range of products and box sizes, and usually where seasonal limited editions appear.
- **Stations**: souvenir shops cluster around Tokyo Station and Kyoto Station, which is handy when changing trains.
- **Airports**: Haneda, Narita, New Chitose, Kansai and other major airports have counters for many brands, good for last-minute top-ups. Popular items can sell out, and limited editions may not be stocked. Check each brand's official store list to confirm a counter exists.
- For some products (such as YOKU MOKU and Sugar Butter Sand Tree), we have only verified prices at the official online shop; in-store prices may differ slightly.

## Carrying refrigerated items

ROYCE' official site says Nama Chocolate must be refrigerated and kept at 10°C or below. When buying at the airport, ask staff to add ice packs, keep it with you as much as possible, and put it in the fridge as soon as you get home. In summer or with a connecting flight, the room-temperature Potato Chip Chocolate is less hassle.

## Taking them home

Food import rules depend on your country, so check your own country's customs rules before you fly. As one example, mainland China allows packaged snacks such as cookies and chocolate within the 5,000-yuan personal-use allowance, bans foods containing meat, and treats refrigerated sweets made mainly of milk or eggs as a gray area; see [Can I bring Japanese snacks into mainland China?](/en/q/japan-food-china-customs/). On the Japan side, purchases from November 2026 switch to paying tax first and getting a refund after you leave Japan; see [Japan's new tax-free rules](/en/q/tax-free-2026/). For everyday snacks from supermarkets and drugstores, see [How to choose Japanese snacks](/en/q/snacks-buying-guide/).
