One Piece: Pirate Warriors Off To A Grand Start In Japan

For the initial launch of One Piece: Pirate Warriors, Namco Bandai shipped 650,000 copies of the game to retailers in Japan. That’s a high number, and it indicates that Namco expect the game to do very well indeed. Given the popularity of One Piece in Japan and Namco’s high expectations, we were curious to see how the game was doing, and so, we perused the blogs of a few Japanese retailers to find out what their experiences of the game’s launch were.



The general consensus is that the game more or less sold out at launch at various stores. One retailer indicates that over 90% of copies at his store (including pre-orders) had sold out. Customers ranged from highschoolers through people in their 20s, and even people over 30.



“Today, on the day of release, an adult man cheerfully came to pick up One Piece: Pirate Warriors,” another retailer echoes on his blog. At this particular store, adults comprised the majority of customers.



Retailer #3 indicates that the game started selling at a rapid speed at his store from the moment he opened for the day. In contrast, a fourth retailer says that sales of the game didn’t really pick up at his store until the evening, but by the end of the day, most copies were sold out.



While each of these anecdotes says something a little different about One Piece’s first day sales, the one thing all of them agree on is that the game sold tremendously well at launch. The golden PlayStation 3 bundle sold out completely at various stores, and one retailer even wonders if more PlayStation 3s were sold with One Piece: Pirate Warriors than at the PlayStation 3’s launch.



As far as new shipments are concerned, Namco Bandai appear to have things under control, with a smaller second shipment being sent out over the weekend. One retailer says that the second shipment consists of another 50,000 copies, but wonders how the game will sell in the long run, after the initial launch is done. Other retailers are instead concerned about stock being able to keep up with demand, and one says that a third shipment of the game won’t be sent out until March 9th.

If this part is true then PS3 sold over 86,742.... I guess near 100k.

Whoa hold the phone, think everyone is getting a little carried away here - these are reportings by separate individual retailers. Just wait until tomorrow when the numbers are officially released.

The game should have a really good opening weekend simply because it's One Piece which is super popular here in Japan. After that I don't know how the legs will be.

The game is getting hammered on Amazon JP. Out of 535 reviews, 207 have given it 1 star, almost 40%! Combined with the 2 star ratings (113 for that), about 60% of the reviews are 1 or 2 stars. Even DQ9 which got bad reviews on Amazon JP when it first came out had roughly 20% for each of the five star ratings (mixed opinions) although the ultimate hits version is rated higher.

Finally I can become a Nakama.

Namco does really great on PS3 this gen.
Between 3 Tales games and this plus all the other smaller franchises they have they probably outsold Square Enix.
